Ferts.. help needed.. what to buy???
I am about to order ferts from Greg Watson.
I forgot which one I need to order to dose PO..
KH2PO4 or K2SO4
Also while I have your attention.. I was wondering..
I have been dosing NO3 and PO on Mon, Wed, Fri and Trace (flourish on Sun, Tue and Thrus)
The system is working well..
I was wondering could I just buy
PMDD Pre-Mix (Contains 1 part Potassium Nitrate, 1 part Potassium Sulfate, 1 part Magnesium Sulfate, 1 part Plantex CSM+B.)
And dose 3 times a week..
I have medium plant load..
