DWC grow in Trouble!!

I tried to upload pic of my suffering babes but the sizes were to large for the site. Description:
Indoor DWC (top feed)
600w HPS
435 Cfm Blower
2 extra fans
Temps- 79-88Ft
GH 3 part nutrients. (started at 1/4now just plain water bc of posible nute burn)
RH 10-20%
3 Choclate Kush Clones from Local Dispensary 6"
PH is NOW a steady 6.0
ppm 300

My clones are either dead or dying. I had a serioud Ph problem towards the begning of my grow whicj I thought I resolved however plants still seem to have no improvement. Its my first grow so Im open to the advice of those whom have gone before me. Today one of the the dead leaves completely fell off the plant.

Yellow leaves-Dried Brown dead Leaves- a white powdery substance stem where rockwool meet.

(Here are some pics I finally Manage TO UpLoad)

More Pics of my BABIES Im a first time grower so im willing to take the advice of any who has the experience over me.

when you had the ph problem, did you flush with low ph water only for 24 hours before adding more nutes?

i had high ph problem with my mystery grow and it caused ph lockout. in turn it caused magnesium and mangnese deficiencies. i flushed with low ph wter only for 24 hours then readded my nutes and adjusted the ph to just under 6.0ph. i had no further probs.

i hope that helps.

My Ph is now perfect 6.0 and ppm is about 450.

The most common "unknown" problem for DWC is nutrient temperatures. You mentioned high room temps so I'll bet a high range on that being the culprit. Don't ever let your DWC solution get over 70 degrees. 65-68 is great. DWCs often use res chillers, etc. I managed to keep my res 10 degrees cooler by just installing a fan into the res. A simple $50 inline fan with a 4" hole cut into the res.

GL!

Ok so i flushed the plants and reservoir system with plain ph adjusted water and removed them from under the 600w.
-I placed them in a bootleg clone dome made from a cooler and some seran wrap. I have periodically placed them into the room only to have them immediately begin to droop so I decided to leave them under a few cfls in the bathroom. They seem to have been doing well the past few days. Except the yellowing that keeps popping up on the edges of new and old growth alike. The leave slowly begin ti brown and eventually die out. Im puzzled by this.
- I'm going to go grab a t5 at Leows and use that as a clone/ early veg to keep my closet temps low.
I dont even have a reservoir thermometer so Ill grab one of those.
-I started spraying the clones with a light (435ppm) nutrient feeding with the mistings. (aid in possible nute def. )
Thanks for the Advice fileEROR404 & 810..

Even on the new growth there is yellowing!

when was the last time you calibrated both of your pens?

Ive been using the ph drops and my ppm pen is brand new which I dont believe needs to be calibrated.
