If your open to soluble salts Ionic has really affordable 1 part product line for coco (grow & bloom formula). I think they recommend adding their line of seaweed and humic acid along with PK boost. You can substitute floralisous plus for both the humic and seaweed products as GH is a better dea,l esp. at 1sp per 5 gallons. Either GH koolbloom or Ionic PK boost will work in flower. I
've used Ionic for hydro and it worked like everything else. When my GH 3 pt runs down I'm gonna grab some and check it on my coco.
As far as pH, you should eventually get something (w an EC too) but test strips will at least get you close, or maybe w nutes no need.
