All air compressor.are in a fresh air filtered box,.I run 2-100L pumps on one system,other a single 100L...one system is a Misty bubble other is a boil.

So

how do the roots look?

Time was up on the grow..roots stained brown as expected with the one part I use,but still strong,kinda bunched up..like a dome,from the air bubbler..I do need to change that system to a mist bubbler like my #2 uses..either way same issue...I am just thinking about changing over to a different nute brand.??
