I also started to use more 0-0-25(KCL) this week and I'm not sure how much to use so I started with 1 cup per day(500 ppm). Because it's so alkaline I pH'd it with PH Down( phosphoric acid). Scrounging around my fertilizer stash,I found some TKO. Ingredient list says phosphoric acid and KCl !! How much do you use ? Other growers please join in.
