White build up on Smart Pots, Is this Mold?

[PrezDickie]

i didn't have any issues like this on my last grow with smart pots but those were 3 gallon pots and these are 5 gal.

could this be mold? Mildew? or maybe just salt/calcium deposits?

its only on one of the two pots in the cabinet. the pot with my photo period BUKU. but that pot has also been on the side of the cabinet where my fresh air intake is so the pot is directly in front of the airflow, it is a passive intake so i didn't think it would be too much of an issue....
plants look healthy so far


haven't seen any powdery mildew or mold on leaves yet, so what do you guys think?

I get it on mine also it is not mold or mildew, It is salt calcium and whatever else is in your soil seeping thru. nothing to worry about

thanks guys, i was having a mini freak out. glad to know its not real concern. so to fully flush these pots i should run what 10gal thru each pot? guess i'm just concerned about over saturating the plants to get them that soaked but since im in flowering now i guess its not a bad idea to do.

Looks like some salt buildup from the breakdown of your nutes. A little flush wouldn't hurt.
