Lack of light or Cal-mag?
Some spotty leaves here at the base of the plant. The overall plant heath is fantastic and dense, haven’t done much defoliation so the bottom gets very little light. Is this a no light issue or calmag? I’m leaning towards calmag but the lower canopy gets very little. Advise?

Leaves keep turning brown and yellow
It all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it. My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead. What do you recon, why could it keep getting worse?

Brown spots on older fan leaves
Spotted some brown spots on 2 of the older fan leaves today. Any thoughts on what the issue may be? Does not rub off- was worried about rust at first. Some more info that could be helpful is that I am using RO water. Thinking about rasing the lights a little higher up too.

Would Epsom salt be helpful for these brown spots? If so, how many ppm? Is it OK to reduce pH with citric acid and distilled water in nute mix?

Brown Spots on Leaves
I've got some brown spots showing up on the Wedding Cake leaves, first thought it may be mold but it doesn't rub off and I sprayed both plants with neem oil about a week ago just in case. Could be CalMag deficient? I use RO water with about 150-200ppms in 3 liters once a day.

Too much light or other deficiency
Too much light or some other deficiency? I’ve been having some issues with yellowing leaves and some other issues with browning and wilting/curling which I thought was initially nutrient lock but what I noticed is all four plants were not stunted and continued to grow normally.
