Ok, these plants are growing exponentially. I had to relocate them to my 5 gal DWC buckets.
They are on the same Masterblend formula, up to 430 ppms and 6.0 pH. Got the fungal leaf problem taken care of. I like to use 1/2 teaspoon of apple cider vinegar with 1 cup of water mix. Spray it on to raise the pH on the plant, temporary killing all molds and fungus. They droop for about 3 minutes then come back strong and clean.
