heres a few pics of some things i've noticed, tell me what ya think. i dont use any fertilizers, but i did try coffee grounds for N. im pretty sure it may have something to do with the soils PH(seeing as i've never tested it). and i know coffee will make the soil more acidic. as far as the canoeing & clawing goes, could my plants be root bound? not sure because my biggest plant shows no symptoms? also for a while i was using lights underneath the plant as well until i read it wasnt good for the plant. the white spot on the leaf has been there for about a week and a half, but hasnt gotten any larger, what could this be?
