Dosing EI dry ferts for the 1st time
Just want to make sure Ive got this all right.
I have a 75 gallon moderately planted (planted well but not very dense). 2x54W T5HO's and 1 regular fluorescent, pressurized CO2.
50% H20 change-weekly
3/4 Tsp-KN03 3x a week
3/16 Tsp-KH2P04 3x a week
1 Tsp-GH booster once a week
15ml 3/16Tsp-Trace 3x a week
4-8ml-Fe/Iron 3x a week
Here are my questions...
I have a PH of 8.6 according to me water report, but it measures 7.2 in the tank, so do I need a GH booster? but im not sure as I cant find the GH on the report.
If I dont need a GH booster would I need to dose K2SO4? The old charts suggest to does K2SO4 but now Im seeing the GH booster in its place.
Also Im reading that with high light you would need the K2SO4... since I have high light would I need to dose K2SO4?
Now I have a 75 gallon but there is 3 inches of substrate in there and a lot of rocks and plants, with that I may have more like 60 gallons of water... my tank is only moderately planted so Im wondering if I should follow the 40-60 gallon or the 60-80 gallon recommended EI dosing chart?
Here is my plan, please let me know if this is accurate (I can adjust if it is established that I need the K2SO4)...

Tuesday----Day3) 3/4 tsp-KN03, 3/16 tsp-KH2P04,
