thank you, randy. This is very helpful.
Could be Mag or Cal or even Iron, if you only started to add cal/mag might take longer to take effect and never clear up just not get worse. I use RO water and add 3ml per gallon cal/mag for what was removed and 5ml per gallon for LED's at both the initial water and all added water.
I always try and maintain at least a 10 degree difference between light and dark and have found mid to upper 80's when lights are on and mid to upper 70's during veg and mid 70's to mid 60's during flower works best for me. Colder night temps will help your plants finish and not drag on for extra weeks
