You were spot on my good sir. You honestly just solved a major riddle I was trying to figure out during this whole damn grow.

This issue was driving me bat shit crazy lol. couldn't figure out why I was getting poor air circulation with my inline fan. I'm growing in a 3x3 with a 6" inline fan I shouldn't have had any issues.
You're the fuckin man. Just removed my prefilter. It was fucking covered in white chalky dust. I removed my plant while I was doing this. Hope this shit didnt cause major damage to my girl.
Jeez I'm such a bone head. Didnt think twice about using hard water for the humfider.
