290w Led Bleaching My Plants

Been haveing trouble w/ bleaching & then after so long it will kill them. When I first got my 290w led I put it to close & really bleached some seedlings I had. Since then I put 3 plants mature plants in there that are flowering, the lite is 18" above the plants & it still started to bleach my colossus auto flower. Auto marie & #1 super auto love it though. The lite is at 4' and I've got 3 seedlings in there as well, it about 40" away. Anyhow I had to remove the tnt kush but the exodus cheese & fruity chronic juice is thriving & starting to get good node spaceing. Just wanted to get some imput from you all. Thanx in advance!

raise the light some more, sounds silly i guess but w/o piks cant no 4 sure as fAR as we no it could b a deficiency of some sort .

Its not a deficiency. Just thought some one mite have had a similar problem.

sounds like a very intense light. I am in the market for a new LED, what brand is your's?

I also have had trouble with bleaching... just gotta keep raising the light.

Its very intense. I got it at growledhydro.com, the guy claims to be a grower since way back & has been developing this lite for mmj for some time. I've got the new improved 290w led, it emits 12 lite waves/spectrums & is for both veg & bloom. Thanx for your response.

The reason I asked for pics is that 'bleaching' issues are not always related to light intensity. Phototoxisity due to other environmental factors can cause this as well. Good luck!
