If you can't get cal mag just go to drugstore and pick up some Epson salt. 1/2 tsp per gal for foliar and 1 tsp per gal for root should do the trick. Spray the foliar right before lights go out.both sides of leaves and add the cal mag or epson normal nute feed but add before all other nutes into water . If you don't have cal mag id go to CVS like tonight and get it going asap.

Hey bro I'm seeeing very clear sign-off magnesium deficiency in those leaves. You need to do a foliar and root drench with cal mag asap so it doesn't duck up.your flowering. The calcium will help bring magnesium into the plant foliar for immediate uptake and then it will continue using it from soil too so at this point I would do both but don't wait too long your gonna start seeing necrosis on the leaves soon. So yeah.. get on it ASAP
