Hey jw whats going on with a couple autoflowers. there a week old, growing great, nice green no discoloring. The tip of the leaves are curling a little. could this be beacause of water thats not a good pH?....... there 12inch under a 600w aircooled hood in ff lightwarrior Also i was wondering if the ocilating fans from a hydroponic/indoorgarden website or store are any differnt from a fan u could buy from a store like wallmart? are they built with the same plastic or could one be a danger , leaching something out of the plastic, or motor into the grow room beaccause of the hps light,ect??? got a 3 pk of nute syringes from aerogarden, they measure in 1 ml/cc increments, and say for single use only on the side..... Can i really only use them once, or do they say that just cause there syringes and i can just reuse them over n over again with advanced nutrients iguana juice? Has anyone used advanced nutrients iguana juice grow and bloom alone? how was it. Anyone have any opinions on it? Looking into getting a vape beacause i get chest pains here and there, which i think might be from smoking alot. Thinking of getting a vaporbrothers vape, any opinons or suggestions
