either way still have some time before its finished. 

 

in the second picture i see spider webs, do you have spider mites?

 

what kind of nutes have you been giving them?

Don't want to drift away from OP's topic, but you made a good catch. I just discovered spider mites at my plants last weekend in the 3rd week of flowering, very devastating. Gave a little hope but trying to fight them hard and so far seems to work: Spray with alcohol/water (1:10) and also spray the tent, repeat 2 days later and spray with Neem oil/water (1:10). Next will spray with bleach and then I hope these suckers are gone forever.

After working 14 years in a company with Thais and Expats, I am working since Jan in company with only Thais. I can say even that is a big difference and I don't like it at all.

Can you not use your Thai bank account - I presume you have at least 1?

Yes and in the past I was going to the counter with a lot of paperwork, but currently I can't do that on working days as on weekends the bank doesn't process international transfers. I am looking for a convenient online solution. I do have the Bualuang app (BKK Bank) and I just discovered that it has a WIR transfer. Need to find out if that's a safe way.

Hi,

I'm a Swiss citizen and need to send money to Switzerland on a regular basis. I found DeeMoney good but Switzerland is not on their list. Western Union seems to charge a lot, for instance if I'd like to transfer 150,000 Baht, the money is about 400 CHF less than the actual exchange rate.

Can anyone recommend me an easy but also secure service? Online instead in person would be best for me.

Another good question Marcus. And I've been curious about it for a long time too.

 

But I'm not sure anyone has the definitive answer to it, certainly I've never seen a definitive answer.

 

My guess is that it's mainly the time factor for Thai sativa grown outdoor in Thailand, as there is no significant difference to the hours of daylight throughout the year.

 

Maybe it's also something to do with the amount of direct sunlight, because in a natural outdoor grow some plants will be in more or less shade.

 

Ruderalis landraces are from Eastern Europe and Russia so they must be affected by light change I guess, to a much greater extent than sativas or indicas. They are much smaller with no significant THC and I believe they were cross-bred with sativas (and indicas) to (1) allow sativa and indica to be grown outdoor in the northern latitudes of Europe and North America and (2) to make smaller breeds for indoor grows. 

 

Indica landraces are from slightly further north than sativas - Afghanistan and Pakistan for example - so they are naturally adapted to some limited extent a seasonal light change.

 

I'm happy to be corrected on the above if someone has a definitive explanation.

 

I'm not sure but I think this was already shared somewhere in the cannabis forum: https://sensiseeds.com/en/blog/equatorial-cannabis-varieties/

Well you can only access soi 16 via the closed road. Alternatively from Rama 4. Going to be hell for me, just living on the opposite of the convention center.

How can someone "enjoying" to research this, except you are a Pedo?

I note experienced folks in this forum recommend slow drying, however I found this report interesting and wonder if anyone tried herb dryers here: https://www.growweedeasy.com/review-herbsnow-dryer-for-drying-cannabis

The conclusion was that if you live in a region of high humidity, this could be an effective solution.

Sorry, the site is not very clear.

Even though you have informed me that the price is for 3.5g, I cant find any indication of the weight for this price.

However, the 3.5g price would make more sense.

 

Which brings me on to my next question:

700 Baht per gram, Who the hell is paying that?

 

I'm quite confident that in about half a year from now top shelf will be around 300-400b/g, middle 200-300b/g and all the rest somewhere below that. Now suppliers are still booked out but everyone is growing and new suppliers will pop up.

Hi,

What do the experts here think of these? They are a bit costly when compared but not silly. Are they maybe any good?

I guess there should be affordable fertilizer for all stages for folks like me who doesn't know what ratio is the best and doesn't have much time preparing etc.

As soon as they break ground you should start to feed them fertilizer Nitrogen, phosphate, potash. I use 20-20-20 fertilizer during the veg state of growth Its regular garden fertilizer. After three months of 18 hours of light when I change to 12 hours putting them in the bud cycle. I change fertilizer too 8-59-8 the 59 is phosphate they need that the most when in bloom. You can flush the fertilizer out before harvest by simply given them straight water for about five waterings and your soil will be ready for your next crop. My guess is over watering the soil should have good drainage topsoil is fine to use but you have to stay on top of when and how much water you give them. And feed them with fertilizer every time you water. You may not be able to get 20-20-20 or 8-59-8 fertilizer it's what I been using anything similar or better should be fine. I have made mistakes and had a good share of them just keep at it gets easy. You have one that looks ok you're going have baby the little one good luck with the other two. 

At three months old these photos are three weeks old. 

 

long way to go yet but have been showing good progress the last three weeks.

They got too tall, so I took some string and made a hook and bent them over the secondaries get more light now. 

     

Congrats, I hope I can achieve same good looking plants once I made my learning experience. For now I have ordered peat moss, the recommended fertilizer, perlite, Mycorrhizal, PH up / down and a meter. Should arrive in 2-3 days and I think I need a lot of luck for 2 of the seedlings.

1. Lowering the lights down onto stressed plants of any age is the opposite of what needs to be done - they are already struggling to transpire and this just makes it worse.

 

It looks like you have this light:

 

https://shopee.co.th/【พร้อมส่ง】ไฟปลูกต้นไม้-โคมไฟปลูกต้นไม้-HEMPEAS-GD2000-300W-Full-Spectrum-with-IR-UV-Grow-Light-ไฟปลูกต้นไม้-i.99442487.3056845466

 

That is a 300W light at full power - it's not really suitable for seedlings. It should be on about 25% power and no closer than 70cm for seedlings.

 

Something like this would be much better (the 6500K version):

 

https://masakigarden.com/shop/led-tube-2f-15w-set/

 

When you have a healthy looking young plant with several nodes and active daily vertical growth then you can pop them under the bigger LED, which does looks like it has a decent spectrum for veg growth by what they put on the listing (although not sure I believe that PAR Chart to be honest - they don't list the diodes by quantity so impossible to check) :

 

 

2. That soil is not potting soil for young plants, as above they are getting locked out.

 

Get some of this:

 

https://www.lazada.co.th/products/plants-center-1-potgrond-h-i2003162624-s6441208580.html

 

Also get some Mycorrhizal powder - this really, really helps get the roots going:

 

https://www.lazada.co.th/products/great-white-mycorrhizae-5-20-i2986387924-s10966581283.html?

 

For nutrients the choices here are rubbish, the best I have found so far is General Hydroponics.

 

The have their 3 part which works well but is fiddly to use, they also have this which I have used on young plants at 0.25 grams per litre (you will need some cheap jewellery scales to use this product):

3. As above use PH corrected water at all times, around 6.2-6.5 is fine.

 

Remember Coco and Peat are inert substrates so PH is massively important.

 

Here are two options for PH meters that can be manually calibrated, avoid the auto calibration unless you spend 1,000 Baht upwards:

https://www.lazada.co.th/products/i122609286-s127996867.html?urlFlag=true&mp=1

 

You also need to be able to calibrate the PH Pens (do it at 4 & 7), so you will need this:

Hope that helps.

 

Cheers.

This is brilliant, great advice and thank you - seems this cannabis forum becomes one of the best source of shared knowledge. Yes this is the light that was part of the whole grow tent set. So I just made the wrong thing by moving the lights closer and I hope they cope with the stress until I am back home. This type of soil was also recommended by another experienced grower. Will do some online shopping now and further hope the plants don't die in meantime so that I can update here on the success.

also, how far away is the light from the seedlings? is there a dimmer switch?

 

if they were fine outdoors and went yellow after being inside, i am also wondering if there is light stress. could just be burning them up if light is too intense

After germination they were light green outside but also started to turn yellow and I thought it's the lack of sunshine these days. So that's when I moved them inside under the light. I put the light (dimmable) about 50cm above the plants. I lowered it to about 30cm since yesterday and one plant looks a bit better now whilst the other 2 still bad if not even worse.

I second the over-watering and compacted soil.

 

Meanwhile Madam's plants are going great guns on slightly shaded sunshine, home-made compost mix (well-rotted garden waste, chicken droppings, coco and sand), along with tap water.

 

I still don't know what's she's going to do with them as neither of us fancy smoking the stuff, it will probably end up in her DIY "herbal" tea (mostly mulberry leaves at present).

Yes my guess is also mainly the soil condition. I started to reduce watering now

15 hours ago, DontDoubtMe said:

looks like a PH / water problem.

 

a while back i tested normal bottled water and the ph was over 7. which is too high. so if you are just using bottled water or even tap water, that is probably the issue.

 

also tap water has many chemicals in it, so if you use it set it outside (out of the sun) for a day or 2 to let the chlorine evaporate out.

 

get a ph pen on shopee (also get an ec pen so you can check the ppm of the water you feed it). also buy some ph up and down. these are must haves for growing weed.

 

coco is a good way to go, but also a proper soil mix is good for beginners as well.

 

the soil looks pretty compact. roots could have being having trouble growing.

 

EDIT:

the feeding on a daily basis is for coco mixes. in soil (especially when seedlings), you dont need to water every day. i used to water every 3-4 days in soil.

 

 

I see most comments are about the soil which seems one of the main reason to me. If your water is that high in ph level them so might me mine. I will start with checking and treating the water and change the soil. Thanks.

They are locked out of nutrients, possibly due to hot soil, lack of oxygen in the soil and overwatering would be my guess.

 

I recently had the same problem growing seedlings in Thai soil that was ready-mixed to grow cannabis. I foolishly thought I could just let them grow in soil and water with low maintenance, top feeding now and again. Within days of emerging they started to turn yellow and were locked out of nutrients.

 

I repotted them in my coco and perlite mix and fed them synthetic nutrients, within 48 hours they were back to life again and a lush green colour. Now they have doubled in size in 24 hours and going great guns. 

 

I have had far better results with coco than soil here, even when have premixed the soil myself. 

Many thanks, so I will order and try out the coco and perlite mix. I noticed another thread in this forum about it which indicates the feeding is required on a daily basis. I'm afraid they may won't survive until the coco arrives but it's the price for learning.

what food are you using ? 

do you ph your water ? what ph if you do.

what is that soil mix you are using ? where was it purchased ? 

what seeds are they ? 

what watt is the led ? how far from the canopy is it ? 

how often are you watering ?

were the smaller ones green when they were put into the tent ? 

 

without being there my guess is over watered and overfed. 

Many thanks, appreciate. From the number of your questions I might need to do much more care.

I didn't give them any "food" or fertilizer yet as I thought too small and would burn the roots. The large plant, I gave organic fertilizer tablets when it was about 10cm high. Also I haven't PH'd the water and using standard soil from a gardening shop. The seeds are quality seeds from Herbies (autoflowering). The LED is a Hempeas GD2000 300w 3200-4200K,5200-6800K + 760nm Full spectrum (grow tent is 1.2x1.2 meters). The smaller ones where greener when I had them first outside but also started to fade yellow and I thought it was due to the recently bad weather without sunshine. So that's when I moved them to the tent.

How should I start to tackle this problem? I guess first check the PH and soil nutrition? This morning I already moved them closer to the light.
