Salts percipitating

[lengado4]

I am haveing some yellow colored salts that started to percipitate out of the water this after noon there was only a change of .2 from this morning. I am running well water with a ph of 8.7 with 326 ppm. I drink it at least i know where it comes from.
Had a problem with mixing and went up and down should I change the water?
I am making new manifold with filter and mixing and sampling circuit.
the seedlings are 9 days old fourth set of leafs starting to emerge.
24 plants.
I am running a nine gal of solution with two 8" air stones.
run 15 min every 1 1/2 hour.
NEW WATER OR NOT.
Thanks have a nice day.
