Anyone currently using this with indoor soil grows? I’ve read great things but it’s all dated about 3-4 years ago.

I started using it last week and have noticed an improvement in my plants (first grow in 7+ years) but was wondering if anyone adds mg, ca or silica on top of using maxsea?

I figure my soil mix has sillica, tap water has calcium so maybe I need to just add mg?

Any advise from current users would be great
