Have a few FLORA-10 lights coming from SpecGradeLED soon. Hopefully that will give a good side-by-side in veg to so see if the Gavita's are complicating things.
Yes, the plants in the photo are about a month old. They're most definitely over kill for veg, but with the dimmers and 4+' we assumed they'd be manageable.
Ah the de POWER! hah but ya I have a hard time getting spaces dialed with mine too. Def burned some leaves and seen some weird growth. Also under fed strains I thought I knew. Crazy how much they'll take up under these. I only have 6ft ceilings...
