could just be shock from transplanting.
Please note, I thought this could be a bacteria or fungus after the last batch of yellow clones, so i stript my room down, bleached all the walls and floors then painted over my walls with KILLS ( paint that kills mold) prior to this batch of clones transplanted!
Before transplanting, All clones had awesome roots (with fine hairs) and for the most part healthy before transplanting into my grow room! THE FIRST FULL DAY AFTER TRANSPLANTING, I NOTICED THE PLANTS STARTING TO TURN A LITTLE YELLOW STARTING FROM THE TOP DOWN! UUGGH!
I am using the 3 part flora series from GH! I started these clones on 1/4 teaspoon per gallon solution! When i noticed the yellowing starting i thought this could be a deficiency, so i added 1 teaspoon per gallon of calmag!
After day 5, i felt that the bleaching could probably be a nitrogen defienciency, so i went to 1 teaspoon per gallon of the three part flora, 1 teaspoon calmag and added floralicious plus to the mix!
Today is day 7 and i notice a hint of green in the middle but really no change!
My room temperature is controlled to vary between 72-78 degrees, my water temperature is exactly at 70 degrees. P.h is always at 6.o (ph twice a day) I have definitely enough light (4 1000 watt lamps in a 10 foot x 16 foot room and the hoods is 6 feet off the ground!)
So, i decided to pull the sickest looking plant up from the rock to see how the roots looked, and 3 strong beautiful white roots poked through the rockwool and they had many feeding hairs! I quickly planted it back!
I cant for the life of me figure out what my problem could be!
Any insight would be appreciated!

It's certainly not humidity. If you've exhausted everything else there have been more than a few people who found different plastic products they were using were leaching chemicals into the nutrients. Think about your pots, resevoirs, hoses, whatever.
Are they all tied together or can you experiement with different seperate systems? What happens is the light heats up the plastic enough to make it leach and with 4kw you have enough light do do that. If that is the issue, just blocking the light from all those plastic parts and hoses may temporarily stop it.
That's not as common as other things though, the first thing I would be suspect about is your water itself and the level of particles that's in it before you even add nutrients. That can cause nutrient lockout type issues even though ph is just fine.
