My bad. I for some reason thought you had Aquasoil in there. But you have Soilmaster.
Diatom algae is common in most any newly setup tank. It goes away after a couple of weeks.
All those "removal" products are aimed at non-planted tanks. And there really is no reason to use them on planted tanks.
Get your nutrients in balance and the rest will follow.
And you might be dosing a bit too much micros if you are actually dosing 3 dry tablespoons a week. That's a ton of iron in there and excess iron can cause algae problems.
