Rust fungus? Nutrient deficiency? What’s happening here?? Only one out of five plants is showing this problem. A couple leaves on one other plant are slightly yellow, but that’s the only other issue so far.
I’m using kindsoil water only method. These plants sprouted Aug 16 (about 7-8 weeks old now). Water about 4.5 cups every 3 days or so. PH my water to 6.5 as recommended on kindsoil website. I have added nothing else, ever.
Gorilla Glue auto seeds bought here at i love growing marijuana.
Coco-loco on top of kindsoil bottom layer. 5 gal fabric pots.
Using blackdog phytomax 400, approx 21” above canopy. 3x3x7 gorilla tent. AC infinity cloudline ventilation. Temps kept at around 70 Fahrenheit, humidity approx 45-50%. lights on 24 hrs. no CO2 supplement.
