You nailed it, this is a calcium deficiency, and since you've already started with a Cal-Mag Foliar spray she should be fine. After deficiency is cleared up, the problem (brown spots and unhealthy new leaves) will stop appearing on new growth, usually within a week. leaves that have been damaged will probably not recover or turn green, so you want to pay attention to new growth for signs of recovery.

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?

Stunted seedlings?#1 looks the same as 3days ago. Their first set of leaves and new growth are light green and curving downwards. Should have bigger and next set of leave? Tested pH of purified water I used and it's a bit high at 7.0. I dimmed the light to 25% from 40. Other ideas?

Brown patches on leaves Noticed these marks on the leaves of the plant I've had problems with. Any ideas what they could be? The other two are smelly amazing and the single plant is so sticky! I think it might be the cheesecake but I'm really not sure, I won't make the mistake of mixing them up again

Discoloration and Spots I'm still not sure if this is a deficiency or some sort of burn. It's definitely spreading a bit more, and I'm unsure if there's time left to address it in the grow. Video of full plant in week.
