Clones shrivel

A couple of the clones I took recently are shriveled up like they got no water. They immediately went into a bubble cloner. At first they went totally limp. Now they are getting kinda crispy. Out of 16 clones two are looking really sad. Cant figure out what I did wrong.

Supercloner14 from supercloset on left. My own creation on right. The one I built has four 4" air stones.

Mine too, man. 5 gal of fresh water with a hint of kelp, vitamin b, and fresh aloe juice. I might try adding more bubbles.

Plenty of bubbles. I used clonex root goo on the ends. Water is ph'd with no nutes. Only difference I can think of is, the two clones struggling were tops. The others were branches. I wonder if that makes a difference?

Kanti, both bubblers have lots of bubbles. The one I built has more bubbles than the one I bought.
