So you will most likely need some cal mag in your feed schedule. Hopefully you have a chart to follow. Your MGB plus cal mag should be enough. I don’t think you need the other stuff and it may cause issues. Unless this stuff is on your chart also.

Agree with @Herb & Suds . With soil (I'm currently using it) I wait weeks for nutes. If not a month. With FFOF you can almost see nute burn on seedlings if you don't drain right.
