How many plants are affected out of how many plants total? 4x4 tent, 4 plants, 2 major infection, 2 starting to show. I take care of my other 2, non-infected tents (different room), before doing anything in the infected one.
Is this a commercial or hobby grow? Hobby
Indoors or outdoors? Indoors
What substrate are you in? Soil blend: 33% "cannamix", 33% perlite, 33% peat moss, 1% hopes and dreams
You say you are “several weeks into flowering”. Are you past 3rd week? Between 3 and 4 weeks
You say you think you got it? Are you SURE it’s septoria? Never sure about anything! ????
Not Ca deficiency? That was first thought. Bumped up Ca, no dif. Adjusted pH to 6.0
I'm going to try a mix of 3tbsp potassium bicarbonate, 3tbsp of coconut oil, and 0.5tsp castile soap --> 1 gallon water for foliar spray. Have clipped all infected leaves.
Also, bugs.
Infection occurred right after moving.
