I transferred them to my aero table after 5 days of cfl growth. Now under a 1000 watt mh air cooled lamp. I have sprouted under the 1000 before with no problem, I already had it running 24/7 for some other plants you can see in the picture. However I did raise it over 3 ft for now. They are growing nice and look very healthy but are very splotchy with lime green and yellowish colors. I have sprouted under the 1000 watts several times with no issues when raised that high.

The rockwool is on top 3 inches of hydroton with a set of sprayers spraying the bottom of the net pot. I have dialed it in where the very bottom of the cube stays wet along with the 3 inches of clay to keep the roots wet. The bottom 25% of the rockwool will remain wet but really not soaked. I then top feed every 48 hours and seems to keep the rockwool not over waterd and perfect.

I was thinking that the 1000 watt light was speeding up the photosythisis more then the seedling can produce natural nutes, so the past 3 days ive been running 180 ppm of gh nutes. Definitely is not showing any nute burn but not helping the yellowish blotches.

any ideas on how to green them up or do you think they will be ok? The roots are not out of the net pot, but are protuding about 2 inches from the rockwool into the clay and look very healthy and fuzy.

Temps are around 78 degrees.

res temps around 72, have a chiller on the way.

any advice? They look a little worse then the picture actually shows.

I know some might say 5 days was too soon to transfer but my tap roots were already sticking out of the rockwool and I wanted to keep them damp and covered by the hydroton. Oh and I soaked rockwool in ph 5.5 and dumped and repeated 3 times for about an hour prior to planting. Now I keep ph between 5.8 and 6.
