Seedlings @ 17 days old showing burns on lower leaves, working upward

I can't seem to figure out whats going on here.

Started EC at 0.2, 5.8PH, they started showing signs of what I thought were being hungry, so I upped it to 0.4EC. Within 24 hours they'd gotten drastically worse so I cut it back to 0.2EC, 5.60ph and the problem still continues.

Surely I can't be burning them at 0.2EC? 100/140ppm just seems ridiculously low to be burning like this.

Can anyone tell what this is from the pics? http://imgur.com/a/2956g

Ignore the upper left plant in the bottom pic, it was an unhealthy clone that sat in the bubbler far too long and those problems were there before going into the DWC tub.
