What would happen if you used 15-15-15 on flowering plants? What will that the extra N do to the plants? If I can use it, can it be used till harvesting? Can I use hydro-prills (Dry Fert.) on indoor grows? Any help please!
You want double the the nitrogen during flowering, meaning if your using 15n, you want 30p. Jack's classic is 10-30-20 and is perfect. Twenty five bucks for a lifetime supply.
