I clone using magic, im actually a wizard IRL... jk, Im using Roottech cloning gel, with H&G Root Excellurator, and super thrive. PH the water to 5.5 or 5.6, try to zero it in to 5.5 best u can. When you take ur cutting have a clean glass of water to put it in after u cut frmo the mother, dont want air getting up in the roots causing drying. Slice it up to desire and dip in cloning gel, stab her into the cube. Fairly simple, strains take longer to root if not flushed prior to cuttings. Cuttings have different root schedules so dont discourage if one roots alot faster than another and they both are healthy cuttings. Yellowing of the leaf is common, as it feeds on itself to get some energy to produce a root system. I snip them off once they are nice n dead, get all that food utilized before i sever it off. Cutting the leaf fingers half way is ok, helps with it not to drag in the tray getting wet and nasty. Its not necessary to cut them either u can leave them intact, its just what i usually do. Hope this helps!
