Switching to dry ferts: some questions


So I finally decided to switch to dry ferts, and ordered the following:

KNO3 - 1 Pound
KH2PO4 - 1/2 Pound
K2SO4 - 1 Pound
Plantex CSM + B - 1/2 Pound
Iron Chelate 11% DPTA - 1/2 Pound
GH Booster - 1 Pound

My tank is 50 gal, low light, CO2 injected, and moderately planted. After reading the "Sticky" by Wasserpest, here's the dosing regime that I thought I would follow:

Monday, Wednesday, Friday: 1/2 Tsp-KNO3, 1/8 Tsp-KH2PO4, 1/8 Tsp-K2SO4
Tuesday, Thursday, Saturday: 1/8 Tsp-Trace
Sunday: 50% H20 change, 3/4 Tsp-GH booster

Does this sound about right? About how long will the ferts last with this schedule? When and how much Iron Chelate do I dose?

If that is the standard EI dosing, then it looks about right.

The fertilizers should last at least half a year.

I would just start dosing EI with everything but the iron chelate first. If you are noticing an iron deficiency, then you can dose it.

Instructions for dosing the iron chelate can be found in the same thread where you found your initial information.
