not much you can do about it now except raise the light back up. those bleached leaves will not turn green again but leave them. if you can hold the back of your hands near the tops of the plants and not feel the heat you should be good.

here is a chart for reference, but the closer end of the chart will def. need cooling for the light. also imo even the closest range with cooling and having the bulb in 1 spot the whole time its on, will bleach the plants anyway. i just cant see having a 600 at 8" away and not have some discoloration to the leaves, but yet people say all the time they have it that cloe or closer.

Thanks s&c ive now raised them back up to around 20" which seems the closest i can get them. Am going to purchase some cooling hoods in the near future i think its only way. Thanks again bud.
