Huge breakthrough in why my grow wasnt growing up to snuff. The very last variable that i never paid attention to was humidity! I honestly had zero clue just how vital this really was. I got a humidifier two days ago and the plants are responding insanely well already! After reading more about it, it seems this is why i kept getting nutrient burn and why the leaves curled up even thiugh i watered properly. It wasnt humid enough at all so the plants were dehydrated and drinking their water way to quick to compensate. I was operating with humidity only in the 20% range! Now i it between 40 and 60% where it should be at this stage. Im trying to dial it into right in the middle at 50%. Only time will tell and i hope i wasnt too late in correcting the problem for these plants but i feel lile im going to start getting the harvests that ive been looking for for the last year of attempted grows.
