Cookies n Creme [Mephisto Grow]

We had a heat wave here in Los Angeles with temps reaching over 110 degrees and the plants suffered in my non-air conditioned apartment, particularly Cookies. It looks like nitrogen toxicity accelerated by extreme heat. Will do the best we can to soldier on with this plant :( They both look kind of tiny, but the environment has not been kind to them. I would say they have about 3-4 weeks left to go. They've actually both only been watered with pHed water the past week, I feel like there's a nutrient build-up. As of Sept 9, CDLC is 64 days old and Cookies is 71 days old.
