My problem is yellowing and wilting leaves that results in dead plants when i move my plants from my veg room to flower room. As a test i have recently moved 5 very healthy plants from my veg room to my flower room but kept all the factors the same except for my lights on one plant and the other 4 receiving varied nute dosage going up and down by factor of .5. Did not matter, after a few days all the plants started showing signs of repeating past failures. After a few weeks all the plants were in critical condition so i moved them back to the veg room. I placed 2 plants under a 3000k light and 3 under 5000k lights, all lights are the same with only the color being different. After 2 weeks the plants under the 3000k were still unhealthy while the 3 placed under the 5000 lights are healthy.

I need help. I have posted pictures of the unhealthy plants.
