Nute Burn & Deficiency symptoms on same plant??

Picked up some teens the other day of various strains and put them into ffof, they came from an E&F system. I noticed the following day a very slight curling at the tips of leaves. I figured it was no big deal, FFOF is a little hot for young plants and must have been for these as well. The confusion is that now, about a week after transplant, 2-3 of the 10 are starting to show symptoms from pic 1/2. It's only one or two leaves on these plants, and it's the older, lower leaves (though not the largest). Red stems on most of the leaves, but especially on these. Any ideas?

looks like too much nitrogen (dark green leaves) and looks like potassium/phosphorus/manganese deficiency.

My longshot guess: soil too wet; roots gasping for air ... cn

Are they clones from the E&F system or the actual plants? I heard you can't switch from hydro to soil and vice versa.
