5 plants in a scrog all on same feeding schedule they are in 5 gal fabric pots of ffof with dolomite lime, about 1month old give or take, I water with ph of 6.5-6.8 all other plants have no issues and even plant in question only has 2 leaves affected like this on different parts of plant so what’s causing it ? Not sure if it’s related at all but this bag of ffof had little black and white gnat looking things that I didn’t notice until a week after transplant..I’ve sprayed the plants with neem oil but no luck they are still there any idea how to get rid of these aswell ? Thanks
