I currently have 7 autos in a 4x4 tent indoors, under 1 vipar spectra 600w and 1 meihzi 600w. I have had them about 20 inches from canopy at 14 days old they have developed yellow/brown dots/holes is this light stress ? It's not say 21, and there is 2 more on the big fan leaves, only had 1 feeding so far was very minute dose too.. does this sound like stress there's is 3 plants with the same thing other than that they look really healthy
