Order of mixing nutrients

At the moment I’m using micro, bloom, canna boost and Epsom salts and I put it in in that order.

Seems like it takes loads of PH down to adjust downwards.

Do I need to change the order of nutrients mixed or just leave it to settle for a bit longer before adjusting PH?

Buy some silica
It will help plants with heat stress,add stem weight support and also will raise ph
Add to water first before any nutes
