Clones yellowing, help please!

[Kingskush]

Hello I've had my clones in the cloner for 12 days, there majority rooting well.
I'm using reverse osmosis water,super thrive, and stumpt tea.
The leaves are yellowing fast and shriveling!
Should I dump the water and refresh it with just RO water and super thrive?
Please help I can't lose these babies!

A dome might help keep humidity in I run mine like this with RO water and cloning powder, with bennies in the water
