Lynn, thanks. I guessed and have done everything you suggested. I,too, wonder why the fungus like growth.

This is newly made batch of mix that has not been exposed to moisture until I moistened it with plain water.

The only thing I can figure is, I have previously used the dome and did not disinfect it before putting on these leaves.

None of the leaves look at all harmed, yet. They are in insert trays sitting in a larger tray. This is the newly planted tray before I domed it.
