4 Weeks Into flowering most pistils are turning red

I use about 1000 wats of tube/CFL in a 3 by 3 foot area.
I have been flowering for about 4 weeks now.
Buds are COATED, but i am not satisfied with my yield.
Should I wait, I have nothing to get a good look at the Tri's
and I am unsure of the strain. Its said to be Kush, I know the bud I got the seeds From was DANK. I screwed my soil up, adding a sand/lime mixture.
My PH was fucked. So I added sulfer to ammend the ph. Its about 3 feet tall, and topped at about 1.5 feet to create 3 main colas. The leaves are yellowing out now. I can grab a pic once the lights come on later to post, but any help would be appreciated.

ya its def not finish by the sounds of things....are you feeding them? u can pick up a pocket microscope from radio shack for about 10bucks...

I have some clones going in some good soil In the Mean Time, but live in east bumfuck and live miles and miles from radio shack or a plant store. The Ferts I use only During Veg, Slow Release Form. High In N. Then I Leech 1 month before flower, every other week. I used a 5x magnifying glass and see no amber colors just clear crystals. So Im assuming I should Wait.
