i'm pretty sure there's some stuff wrong. but i only've ever done hydro so i shouldn't be too pretentious here.

the soil isn't perfect, for sure. i know roots like oxygen, and i'm not sure how good the drainage is in that top soil. perhaps adding some perlite/vermiculite?

i'm sure a lot of people might chime in and lecture you on not having 3 plants in the same planter.

also, you don't want to be feeding every watering. salts and whatnot will build up. try a water, water, feed, repeat cycle.

i hope some soil pros jump in and give advice. other than that, good luck and welcome to the CFL grow club.

stay safe
