will take some photos to help alittle more.

First, how do you keep the temps down without venting with 2 x 1000W?

Unclear on the ph of the water you actually are giving the plants. You say it runs 7-8 and adjust with ph Up?????

How long has the plant been in this pot of soil?

Any pictures of the leaves.

Could be lockout.
Could be nutrient def
could be high ph.
could be root bound

the room has an ac window unit installed the room is kept at a fairly constant 75degrees day and maybe a bit cooler at night say 70-72 they are being watered with a ph of 6.5 the run off is sometime a bit lower 5.5-6. i use ph down to lower the ph and ph up with the nutes since the nutes drop my ph so far

picture one is 3 weeks ago this is one i kept out they all looked like this.
picture two is a general view of the flower room
picture three a bit blurry but this one has some of the yellowing
picture four you can see the yellowing
picture five same picture without the flash

Well, this appears to be normal yellowing during the flowering phase as the plant stops using nitrogen.

thank you wash i was torn and really needed a second opinion on the matter just wasnt expecting it so early on i suppose:)

Just a guess, you are about 4 weeks into flower right?! You need CalMag.

Ok, hang on... Is it the tops of the plants? The 4th pic looks all green at the bottom and yellow/white on top. I see you have 2 1000W and the plants are 1.5 feet from light. Too close. It may be light bleaching. Go to about 3 feet away from light.

A 1000w HPS light should be at least 2 feet away from the plants. You're burning your plants. Raise the light about a foot. Even 3 feet away with 1000w isn't too far. :pimp:
