:smoking: you know, when it's all going well, great as that is, you learn a little less... it's the "hiccups" that force you to dig deeper, learn more faster, and learn things not usually dealt with when a grow is rolling along well! Find some books on cannabis growing, I think The Cannabis Encyclopedia is a nice starter book, and covers a wide variety of topics....
Foliar sprays on both sides of the leaf are best, but the bottoms do have more stomata (moisture/gas exchange openings) and so absorb more there,... Usually you treat with foliar 2-4 times over a week or so, every 2-3 days... you can respray with clear water once after a treatment, to help re-dissolve the salts and get a "second helping" of sorts, plus it rinses away the excess,... if you see build up on leaves, rinse them off, but likely you won't if you keep the dilution low... After that, see if just feeding through the soil maintains things....
GHE, follow the label directions for soil dosing, 1-2 times in a week,.. you want to give some time for the foliars and the soil treatments to get working, over several days.... it very possible to over-do Ca and Mg!
