Root Rot, Over Watered or ?? Help!!

Some good advice here.
And I think you are spot on with your pearlite statement - I don't see any & with out the drainage your soil can retain a lot of water.

If I were to guess, I'd say too dense of a media, over watering. And then there's your temperature issue.
 
Looks like you have them sitting on that insulated bubble foam, could be wrong on that? I think that should be enough, but a heat mat would help. I have seen people selling custom sized heat mats on ebay, might want to check that out. When I had my issue I put the pots on thick cardboard and it really helped. They were on cold concrete before that.
 
Anyway don't give them more than they can consume and you won't get salt buildups. One caveat.. I guess this could be a problem if you are watering with extremely mineral-laden water but I think this would be uncommon.

If your water source goes through a water softener, you WILL get to know all about toxic salt build up.
