During veg the plants remain pretty green, some yellowing but not too much. During the flowering cycle the leaves become yellow or brown and die quickly leaving me with sad looking fluffy buds. i have 2 1000w lights for flower and a bunch of cfl bulbs for veg. I'm certain they get enough light. temps are good and stay around 76. gh organic nutrients used at half strength from directions on the bottle. Reverse Osmosis water. Medium is 4 parts black gold soil 1 part vermiculite. Plants need water about once a week. I have a 400cfm fan for exhaust that pulls air through about 20 feet of ducting with a charcoal scrubber on the end. Intake air is a 200 cfm inline duct fan from home depot.
You can see the new plants that have been flowering only for a few days are still green and somewhat healthy then the other pics are 7 weeks flowering and looking very sad.![IMG_0064.jpg](/data/attachments/1982/1982075-d385e554e68d6a55c78c4ee796d4f40c.jpg)

Could poor air ventilation be my problem?
PH is probably a little high ill check that and repost.
Maybe more vermiculite for better drainage?
Is it too much light in flower room shocking the plants?
Any help is greatly appreciated. Thanks in advance
