Clones-lower leaves turning yellow

[markhug]

I planted some clone in rockwool, 4 days ago. Ph was balanced at 5.8. The first 24 hours I had problem keeping the temp below 85 degrees.

I reloctaed them to get the temp is regulated at 76 degrees. humidity between 80%-86%.

The lower leaves have been turning yellow for the past day. They are located under a dome which I remove the dome for 15 min. in the am and PM. the
top vents are one quarter opened.

The is my first attempt using rockwool. Is there anyway to correct this?

Any guesses where I went wrong.

I'll cut the yellow leaves off and pray for the best. This will be my first attempt at hydroponics, and I don't think that I can take them from soil into hydro. The clones were
only started 5 days ago, they probably don't have a roots yet to feed. How about a foilage feed.
