Brown spots on leaves, I thought it was Cal related, and tried different doses, with no success. Could it be VPD related? It can and does get very hot and very humid in the 1.5ftx2.5ft closet. Even when running no humidifier (Live in AZ). I've been struggling with this for months

The only thing vpd will really effect is rate of growth and over all yield come flower. This is more of a ph issue with your reservoir always keep an extra ph pen handy or even some strips as a sanity check.

It should be stated, this is done in Hydro with 20ml of CalMag for 3.5 gals of water.

10000000 % ph related calcium issue.
Meters lie, even most exoensive or brake sometimes.
Could be aftermath of light overwatering , that swings pots ph, aka watered while pot was still a bit moist.

I see that it is in bloom and consequently it eats more, the spots may be due to a lack of potassium or magnesium, but very often it is a problem limited to a few leaves, practically nothing is perfect ... keep it under control in the days to come, if it gets worse it needs more food, if it stays the same then it's a limited problem.
