Does anyones nutrients leave behind a white salt on their trays?

I bottom feed with garland trays as the mylar tent spill trays kept on leaking but it is still leaving behind a white powder like substance, when I go in the day after feeding the water still in the tray has this white stuff sitting on top of it, are my advanced nutrients not mixing properly? What pump can I get to put in the garland trays and keep the water mixing?

Nothing to worry about, it's happening with my ff at only 1/3 of a dose

I just worry as it's a lot stronger for us using drip trays as bottom feeders instead of drip trays I dont know what the white compound/powder is to study and find out if its harmful or how to reduce it it's about the only thing I havent mastered about having a spotless plate.

These salts adont join the next feed and give nute burn they just keep staying but are easily brushed off with a finger I'm just worried bacteria flying everywhere as I do that

I have ordered a submersible fish tank pump that looks small enough to go shallow enough to work if this mixes it enough to ensure the nutrients dont unbound from the liquid I will order more and post update

This should solve the problem
