PH is between 6.5-6.8.

Whats going on?So.. 6th week into it. My leaves have various brown spots and yellowing spots in no particular spot. There is some browning on leaf edges. Also tips are up. I am thinking cal mag and to much heat. But not sure. I lifted light up and so far nothing. Also started adding cal mag .Week 6

Nutrient burn symptoms?I may have slightly burned my plants based on the burnt tips. But do tiny brown spots near the tips also mean the same thing? Also some leaves are not completely greening out:s I know I’m not over watering the pot either. And they are getting cal/mag. Also grown in fox farm soil.Feeding. Deficiences

Calcium deficiency, cal-mag now in hand, water now, or wait for normal scheduled water? Last water yesterday.Plants are suffering from an early stage of calcium deficiency, received a bottle of cal-mag today. Watered last night cause I didn't want to wait any longer. Should I wait for my next water (2 more days) or give a single dose of Cal-mag now, to get some calcium to the plant?Leaves. Color - Dark-brown
