If you have a 1000w hps i think it may be a heat issue. I keep mine below 80, Later in flowering i even experiment with super low temps for extra frosting.lol. also, what have you fed her on? i use bio-bizz bloom/grow with loads of mollases and i turned what is in my opinion a slightly inferior strain (top 44) into something smokable on my first grow.
I use a 250w hps in an area that is never sealed (ghetto ventilation), I have a kick ass fan That helps keep the temps around 76 and i use the specified nutes. This is what i came up with for a first grow (the pics suck) lol.The main problem i had was keeping the kitten out of the grow space ( he loves the heat).lol. Is it cruel to get cats stoned? i mean he always comes and sits with us when its smoke time and its not like a give him blowbacks or anything lol. he just loves the hotbox....sorry totally digressing lol.
P.S. A lot of my beginers luck comes from that i live in england and in the winter the outside temps are awful! it helps keep mine down though.if u wanna c more just check out the complete journal in my sig
