Potassium phosphate

i found a bottle of potassium phosphate and on the bottle it says plant mineral deficiency kit..so how do i use it and what will it do to my plant??

I have a nutrient solution of 12/55/6 and I was wondering is the potash high enough. O yea I was growing a feminized rocklock and all of a sudden it turned into a male why is this.

Well clintsy I would think you add maybe a teaspoon to a gallon or something but I have never used this before but thats what I would do.

no one else?

i have potassium phosphate in dry form, basically it provides your plants with P-K but not Nitrogen. i use it in high ratio during flowering and in lower ratio during vegging but it's not a complete plant food. if you have a high Nitrogen fert for vegging you can skip buying a bloom fert and add to it the P-K to make a good flowering recipe
