ok so i take back anything negative i said about DM Zone. Whatever was threatening the plants' roots is definitely losing the fight. the Roots are really pulling through and the plants themselves looks as though they have been shot in the veins with life. no real explosion of growth or anything, except the roots themselves to some extent, but they do look like they can run a 5km marathon, albeit with a smoke break here and there. in short, DM Zone worked for me.
but i think i need to get some humdity in there. The leaves look to have that V shaped cupping which if i remember correctly is a physical sign from the plant that has to do with little humidity in the air or something...? if anyone could clarify on that issue id appreciate it very much
