Help with cloning

Yo, I need some help. I cloned some plants about 5 weeks ago. The problem is that I put the newly rooting cuttings in miracle grow and it over fertilized the clones. I have now 16 clones that have grown roots but have no new growth. The other 8 have roots and a vigorous vegetative growth. Will the clones that have shown no growth start to grow? Or am I just wasting my time?

If you have 8 good ones cool.
If over two weeks and no new growth, they are deffinetly stunted, won't produce like the others.
No space? toss them Got Space? grow them together SOG style or outside.
