Looks fine to me maybe some calmag added but could be your high ph tap water, try lowering it a little when feeding.

Looks good! Only thing i see is nitrogen toxicity which could be leading to a lockout. Dark green leaves, tips are curled down. Might look and see what your nitrogen levels are in each supplement and cut back on one. You dont need near as much nitrogen once you hit flower stage.

Lock out from to much nutrients in the medium. Quit adding guia green. Your nature's living soil shud work fine on its own. To ph down in organics I just use pH down. Wont hurt nothing
