Still having loads of trouble with light burn / stressed out plants. Leaves pointing up, turning yellowish. Lights are now even at 80cm above plants, can hardly go any higher. I'm surprised, because the Hans Panel 180w is used at 30cm in numerous grow reports online with no issues. Must be the combination thats too much. 420 watts in a grow tent, and leaves are burning alive. If that ain't proof that LED's can't 'outperform' HPS ;)
Does anyone have tips & tricks for making my plants healthy? It feels just silly to remove a light and continue with only 180 or 240 watts total.. Should I use CO2 tabs or something? Do they actually work at this point? Questions questions.
