Chlorosis Problem

Have a plant in 24/7 under a 90 660nm LED UFO light using direct water culture. The upper leaves are a pale yellow, some are even white. The shaded leaves look dark green. I've slowly increased the nutrients to 200% General Hydroponics veg formula. Some of the bottom leaves show nutrient burn, so I've backed off to 150%. Root production is impressive.

Is this chlorosis due to a lack of blue, or too much light?

i have kno clue to ur question but was wondering how you like ur UFO and where u got it and how much $ was it?? i bought one like 3 years ago off ebay for 150+$ and its the worst piece of crap ive ever bought. I still have it put away somewhere. But honestly, i got better results using one 26 watt cfl that the 90 watt ufo. im guessing i just got ripped off cause i got it off ebay and it came from fking china

Chlorosis just means the plant is producing insufficient chlorophyll. Could be because of a thousand things. Ph, nute burn, insufficient light, etc*.

Were the plants fine before the nute burn? Maybe you water logged the roots or maybe it is just a deficiency. Which specific nutes are you using?
