Good day,
I would appreciate any advice or experience with this problem.

OK, 9 plants grown in 3 gallon mesh bottom buckets. Current lights: 400w hps and 400w MH. Mix is Tupur soiless 65% and Tupur organic potting soil 35%. Plants are clones 3months old hit with temp problems 38f to 100f. PH. is 5.5. Transplanted twice, flushed three times. watered every 5-6 days with mild Age old Kelp, Ph Down, Super thrive, age old grow. Current room temp is 85f.

Possible Magnesium deficiency. Watered today w/ mild epsom salt solution.

hmmm it's looking like they are nitrogen deficient. Possible mag deficiency I don't know. Here's what I would do. Up your nitrogen intake to plants by adding urine ( not sure of the mix, look it up it's posted around) it actually works I did it as a teen and my plants always darkened up to a lush green. Make sure that your ph is correct. Use better balanced food. If they are not getting fresh air, make sure by any means that they are. Try all of this and see what happens.

I don't think pissing on your plants is going to fix anything.

I do see evidence of Potassium and Nitrogen shortage. I see evidence of Phosphorus lock out due to low temperatures. There's some pH damage, some heat damage, and what looks like some recent nutrient toxicity.

This plant has been through so much it's impossible for me to say what, if anything, is wrong with it now.

If you are worried about her and want things to be better I'd suggest flushing the media to remove any build up and feeding with a good balance of NPK Ca and Mg. Keep your pH constant (I'd go closer to 6.2 if I were relying on organics) and your temperatures closer to 75 degrees and that'd fix most issues that aren't pest or mold related.

Stop flushing, you got ph issues. its too low resulting in your plants being unable to take up vital nutes such as N K and Mg. Buy a good quality meter get it 6.5 in that medium. Wait a week and they should show signs of recovery.
