Clones turning yellow

Took clones 8 days ago and put them in rapid rooters. First sets of roots just started to poke through today but on 6/12 clones the leaves are starting to yellow. What should I do to save them if there is anything I can do?

Nothing you can do, its just they are overwatered, if roots are coming out they will be just fine. once they start vegging the yellow will turn back to green. Very common, 50% of my plants get yellow leaves on them in the aerocloner. They all come out just fine.

Most likely nitrogen deficiency - when are you putting them into their pots? It's pretty normal for leaves to yellow when cloning - the plant needs nitrogen for root growth and the leaves act as stores for nitrogen. Don't worry about it.
