plants are about 2-1/2 months old. i had a lot of problems with temp and humidity being so cold here. i had some ph problems too....root rot,drip heads clogging,general clumsiness.
I thought i had it all "dialed in" until i switched to 1000w hps last night. Now its too hot when the lights are on. LOL.
Theyve been on 12/12 for the pas 5 days.
