Im about to run out of moab by mad farmer, and i still have 1-2 weeks i want to feed, (week 7-8 1/2)I do have some shooting powder (h&g) though and i know their pretty similar, but worried about minerals and chemicals that differ between the two and throwing my plants off.
Would it be okay to start useing the shooting powder soon as the moab is depleted?? Or should i just not bother?
