Growth on Roots?

I'm growing an auto strain and I'm at 5 weeks from sprout.

Started the grow in an Aerogarden and moved them to a DIY bubbleponic system at 1.5 weeks old. They are still in the Aerogarden pods.

I've only added a very small amount of nutes at 4 weeks since I have other younger seedlings in the system.

I just noticed this growth on the roots today. Please tell me it is only salt build up. The only thing about that is, this is the only roots that have it out of 5 plants in this system. The top side doesn't look bad. It has been growing at a slow rate lately but looks fine. Please help!!




Check out the journal link in my signature for more information on this grow.

Is this root rot?

Any ideas?

looks like salt. It also could be shock from the transplanting. gently nute and perhaps a flush is not out of the question??? search salt build up on RIU and u may find similar pics that could offer the best advice. I'm an organic soil farmer and every time i got salt build up i would flush like crazy, wait 5-7 days and start mildly nuteing. Organic nutes have really taken these variables out of my grow. Blue mountain organics are the best fro nuting/ferting/

Well, I flushed twice this last weekend. The white stuff is still there, but all the plants have responded really well from the flushes. I also added a low dose of fox farm big bloom to the res. It is low in N so I thought it wouldn't hurt the younger ones.
