Hey Ray, welcome to TPT!
Your parameters should be just fine for those plants, and other than maybe bringing GH down a touch, I'd leave it as is. My parameters are pretty much identical except my GH is 6, and I haven't found a low tech plant that won't grow for me yet
Just as a warning, the FugeRay puts out a lot of light for that height of tank and does not have dimming as far as I know (raising it or using window screen are options). Your micro words and myrio do like medium level lighting (which you'll be well above), but you may have to work at finding the right balance to reduce algae issues.
Lastly, Equilibrium contains potassium, calcium, magnesium, iron, and manganese, but you'll still be missing nitrates and phosphates (both can come from fish food and waste), boron, copper, molybdenum, and zinc. Sometimes these minerals come in your tap water, but with RO/DI, you'll be removing all that.
Dry fertilizers are the way to go and will last you a long time. I personally use the EI with CSM+B and GH booster from @nilocg
(a forum member here). Here's the full packages on his site: http://nilocg.com/dry-fertilizer/packages/
He's really responsive if you have fertilizer questions, and there are other brands people here use like Green Leaf Aquariums, CO2Art, etc.
