Started using RO water and increased the nutrients. As you can see, my fourth plant (a freebie seed that came with the others) turned out to not be an auto and is kind of taking over the tent. I started leaving her out of the tent in the dark for 12 hours overnight. hopefully that'll flip her into flower. The buds are fattening up and are becoming pretty frosty. I am starting to see some of the hairs turning orange which is a good sign. They seem to becoming healthier. Will be monitoring trichomes over the next couple of weeks.
