Upon changing water last week I began to notice burning on the tips of the leaves… at first I had thought it was ph problems and an iron deficiency since it had began on lower portion of plant my hypothesis seemed correct but I had found otherwise throughout the week that had just not been the case… upon more research on floraflex I found that it calls for no cal mag and that is now what I suspected to be the culprit of my problem is now nutrient burn… i gave her a flush at beginning of this week as well as a new set of nutrients our ppm is half of what it was now im sitting at .8 ec and kept the ph lower to 5.8 to ensure we can intake all the nutrient value needed… still adding frozen water bottles to the bucket as the temps are still high but also noticed my peroxide has gone bad so I fetched a new bottle as i began to notice root rot beginning… cookies strains are tough to grow! I knew this would be a challenge and im still up to the task! I will be ordering some hydrogaurd as for once peroxide is not doing the trick! Anyway im expecting at least another week of recovery so probably not much in the upcoming diaries but i will keep you updated!
Get a chiller for that water or you’re gonna have issues man. I tried the exact same setup. The black buckets attracted heat and make it impossible to keep cold enough to not have bacteria.
