Thanks @Seattle_Aquarist

So basically if I manage to get SeaChem Equilibrium all I need to dose is 1/8" and 1/32" teaspoon of KNO3 and KH2PO4 per 20 gal. once a week (Tom Barr non CO2 method) and there is no need of K2SO4 and MgSO4?

If I don't manage to get Equilibrium, will only KNO3 and KH2PO4 + root tabs have positive effect on the plants or it's better not to use them at all (may cause algae bloom?)? The tanks is running since August and I don't have any algae problems (I had only diatom algae but not anymore). I do 30% weekly water changes.
