I was about to soil drench my pots because I saw them in there but I noticed one on the fan leaves just right now…

what do you guys think?

PS I know the plants have deficiencies I got a little over my head and went overboard with clones and had to cramp 20 3feet plants in 0.5gl pots (literally 20 lol) in 1 bathtub so forgive me if they look sick Lol
