Plants not showing any signs of THC?

i wouldn't count your eggs, yet... but... obviously not a good correlation regarding limited trichomes... if it is still stretching, good chance it has a long flower period, eh? maybe, it'll pile on at end. pic 5 looks overfed, but i cann't tell as easily in others -- glossy, dark, skinny fingered leaves (unless it's a normal trait for that plant)... this could simply be lighting and picture-related confusion on my end. take a leaf into real light.. if it is glossy and dark, it may be related to how you are fertilizing, but only relative to genetics... i.e. i doubt this is a linchpin to drastic change. long skinny fingers on leaves, if not normal, can be caused by excess P and K which is popularly believed that you can just dump this shit on a flowering plant and it will "grow big buds, dude!" ... while it may help when applied with common sense, a lot of times ppl just burn the shit out of their plants and convince themselves it is helping while never having a proper baseline to compare in the first place. it's not just what we see that factors into potency.. so can't assume it even if correlated. give it a chance, and i hope it turns out better for you.
