Can you help me identify my problem?

They stand in Hydroclay and get watered every 20 Min.

Please Help me!

Looks like you know what you are doing. I am NOT familiar to hydro-clay. To my eye it looks like magnesium. I would suggest CM to 0,3 than epsom salt till 0,5 and rest. Keep EC where it is. my noobish advice, maybe some hydro Geeez can provide more useful advice…
