Purple Haze

So let me start by saying I wanted to top and do a bunch of training to these girls but this laundry list of issues have stopped me from doing anything other than finding the answer. So as I was saying in the previous weeks, I have been treating this like a coco grow and watering everyday at a ph of 5.8-6.2 so I can get a better spectrum of nutrients available to the plants. Admittedly this is my first coco grow but not my first grow in general. As the days have progressed I start noticing my plants showing signs of stress, that stress came in the form of heat, light, nutrient burn ,nutrient deficiency..I know what a cluster of what the actual fuck. I am active in many subreddits, ilgm forums and reached out to my fellow peers to weigh in on what could be wrong , the general consensus was not watering everyday and at a stable ph of 5.8 and heat stress and light stress from the obvious tacoeing leaves. I really couldn't do anything about my humidity levels because of my flowering plants{downfall to no extra tents/space and risk rot and mold. After all the info I received I decided to do a test, water everyday {even if they felt heavy af} and let my other auto dry out more, like soil because I exhausted all other options, I checked the run off ppm and it was higher than snoop dogg on 420, it came out to around 4500-5000ppm. Having knowledge of safe ppm levels I instantly new this was way to high. I did some research and without the proper expensive tools I couldn't accurately test my ppm because of the slow release dry amendments, I also checked the runof ph and it came back at 5.1 so i knew I was out of my nutrient spectrum .So i decided to flush my purple haze and blueberry brought the ppm down to 900, using tap water because i didn't have 12gallons of ro water available, my tap is a steady 350ppm so i should have a lower amount of nutes.
