White Widow issues

I presently have 40 plants of White Widow (derived from seeds) they are under 6x1000 lights. I toped a few but the ones not topped are growing into the lights. My concern is the temp. 81-84 lights on w co2 they were veged for 60 days and have been on 12x12 for almost a month. I keep ppm @1000= or - 50 any insight or suggestions Anything on the subject of w/w or growing period will be appreciated

Is there someone out there that has a formula for feeding white widow I am used to Canna products but I lost my recepe Help pss. we are talking indoor

LST them bad girls. thats only 150 watts per plant, I try to stay at 200 minimum, but thats just me

My issue is heat and since ww is a hybrid I am not sure about 81-84 degrees I have 6 plants under each light in addition to about 6 florescent lights on the walls to get the color spectrum. I am no genius and would welcome any input
