Maybe I wasn't feeding early enough..... Mine look tiny to @Newman’sOwn .....
Your megacrops look great. Feed wise water only RO and rain so far for my plants. Solos had a layer of amended seedling mix at the bottom
and the transplant soil is reamended COM Stonington blend
though I think it’s the tent conditions more than anything, and my soil was borderline too hot based on the brown spotting that occurred on the early growth but they seem to have grown past that.
