Growing under CMH or t5? Oh you said it right there..Mars..... They look great but very leafy-bushy, you may want to supplement with an additional small HPS (250w) to get them to stretch up a bit and grow more solid nugs. No idea of plant age or your setup but in my tent I’d guess 2-3 oz from one of your plants, so 6-7 total with the right levels of light/nutes. Good work!
