Coco Melon Clones

I've lumped all 4 of these plants into one grow. The three in the R box look like they may be taking a beating due to heat, though the healthier looking one in the L box is also shedding a lot of leaves off the bottom all of a sudden. I think this is related to the amount of flowering confusion these clones may have gone through earlier. I have been keeping the nutrients light for now but may feed some bloom soon.
