your source of P ?
 

ron

hi there what is your source of P ?

you see, i tried using Monopotassium Phosphate as my P source and it turn out to be a failure. 3 weeks into that chemical and it seems my roots ain't growing the way it should

when i change to Peter's Hydrosol, just in 12 hours, new root hair starts to pop out.

wonder if you have answer to this mystery

thanks

I am using a :
5-11-26 Hydroponic Water Soluble Fertilizer - 5 ounces
Calcium Nitrate - 4 ounces
Magnesium Sulfate - 2 ounces

I mix all three in a blender with enough water to liquefy it.
Then I mix that to my reservoir and use my meter to adjust to the correct ppm and pH.

Correction

I was just informed by someone who knows that I shouldn't mix the Calcium Nitrite with the hydro mix because of conflicting chemicals.
So I will add the Calcium Nitrite separately to my reservoir.
I should have known it was left out of the hydro mix for a reason.
