What do you think

Early miss autoflower in soil - nutrients every other watering I am thinking its a calcium or magnesium deficiency and will be upping the calmag next watering -Other opinions would be appreciated

Sure looks like a cal/mag issue. Easley fixed. Add cal mag, ph to correct value.

What kind of lights and how close? First pic, plant in the foreground has some odd curling on its leaves. Possibly light stress?

I have 1 mars ts600 and 1 ts1000 = 250w in a 31/2 x 31/2 and around 15 inches away

well according to mars that distance is fine. I was just fixated on the cupping tips of the other plant. For sure add some calmag, i do every feeding and usually go a tad more than feed chart suggests. Hope you get it cleared up.
