Hi gwe new inside grower , several years outside but finding out now I didn't really know much.Third grow inside first with limited success, with help from gwe did 18 on the second with 4 clones off first in a 6x2 space. 400 watt hps conversion lamp and a 300 galaxy hydro. So now on my third clones again off 2nd in fifth week of veg. This time in 5x5 tent,1000mh_hps ,air cooled reflector,in line fan. In 7gal fiber pots with roots organic camouflage bag and 30%perlite. Pure essentials nuts ,cal mag , tap water. Temp 75 with lights on 65 without humidity between 55 and 65 run off pH 6.4. Over the past week and half when I water plants get droopy , new growth the most. Happens right after watering, the next day they look fine droopy the next . By then they need watering again. Tried waiting another day thinking I was over watering but by then I'm supper dry. Previous to this had yellowing in new growth due to high ph. Thinking root bound suggestions apreciated thnx.
