Buildup on outside of fabric pots?

So what am I supposed to do about this build up? I've cleaned the outside and within a week its back! Is it hurting anything leaving it on the pot until harvest? After harvest I just wash them but until harvest im worried that the build up will cause problems. Its hard to get to the back of the tent to clean the pots but I wanna know if I should keep cleaning weekly or if its not gonna cause any harm

it's fine. Just don't let them dry out.

Don't do anything. It doesn't hurt anything. From the white salt build up. To the algae. The biggest concern is knats will infest the bottom of the pot. So watch that area.

Yeah gnats have arrived. I just got rid of them too. But gnats and larvae won't hurt adult plants if you keep them under control. I just hit them with peroxide and yellow sticky traps every week or 2

I'm going to invest in pots that don't do this though. Anyone? I only use 3 gallon. I've seen some fabric that don't get the buildup apparently but they're like 12 fucking dollars a pop

Probably worth it. Since you have the bigger tent it may be worth it to scrog that bitch up with 2 - 10gal pots Lol I can’t wait to move on to another tent size.
