Burkle and Mandarin cookie Aerogarden

if theyre getting droopy root issues is a possibility. as i remember your reservoir temps were high which decreases the dissolved oxygen in the water drastically and promotes bad microbial growth. i know you use hydroguard but sometimes thats not enough. as for too much nutes. yeah 600ppm is too much for those little gals i’m not a hydro guy but half of that could work better i guess. however as i mentioned your setup is for growing lettuce and cannabis is a high energy plant and requires higher intensity lighting. all youll get in that setup will be spindly clones.
