i start adding mkp around the end of week 2 of 12-12, when they start to set flower. i reduce jacks a bit when i start using mkp, so i run it at .5g/gal. to determine application rate, youll want to calculate elemental ppm (i dont recommend winging it). there isnt really a "one recipe to rule them all". if you are happy with your current nutes, you could calculate their elemental ppm and diy it with the dry stuff. a lot of folks run the 321 recipe from start to finish with good results. some folks run a lucas formula recipe. lots of room for customization with dry nutesI assum these are basically a PK booster? How much do you use and when?
