EZ-cloner problem new leaves yellowing and twisting over

I have a 120 site ez cloner. ph is 5.8 ppm is 220 using a little Bcuzz Roots. Root structures are over 12" long now, do I need to raise nutrient levels? They seem fine, usually its the older leaves that yellow and die off a little. This is happening on fans of new growth at least one in the set. Sorry for crappy pic. Will upload more if needed.

another picture showing the leaf twisting, after the yellow out from middle of leaf inwards and begin twisting

Not too familiar with the Bcuzz roots. But is that just a rooting hormone? If so you may want to switch over to reg veg nute if the roots are already growing.

sounds like the ezcloner did its job.

now its time to move out of the cloner and into whatever meduim you will use to veg them.
