You are experiencing progressive potassium deficiency. Light nitrogen and heavy potassium are phosphorus in flowering. Good luck🌱

Dark spots starting after feeding. Concern? CalMag, first time feeding with more nutes, so it might be nute burn yea but is it a concern. It started moments after watering, or that's when i noticed it. On a few leaves. Earlier on i cut lower buds and did some defoliation

Leaves brown down the length of half the leaf
I have some leaves that have gone a bit brown down one half, but along the length. See them in Day 40 pics (I have added a extra comment there). Does anyone know what that is? I was thinking maybe it is just the bits that have been sitting under other leaves, but I am not so sure

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?

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.
