This is a white widow Auto, in coco, pearlite mix about 70/30 in 3 gal fabric pot. In week 2 of flower under 24 hrs mars hydro tsl 2000. Running about 76-80° f and 50% +/- rh. Started getting brown spots last week. Feeding GH trio @6.3-5 ph and was giving call mag until I ran out. My question is does this look like a cal deficiency. I ordered humbolts call mag plus iron but not here yet. Anything I can do till it comes? Thanks
