Read the bottle, I believe the suggest 3-4 teaspoons for a regular feeding. However if these cuts are that young I would just suggest letting them get a foothold before dousing them with nutes. If you are using Oceans Forrest or Happy Frog soil they should be good for about a month with little to no feed.
3-4 tsp would be an aggressive feed for a mature plant. I'd feed at 1/4 tsp and then ask the plants how they feel about it. EC up, pH down is too rich. EC down pH up is too lean. EC and pH flat sounds good on paper but, no one reading allows equal absorption of all nutes and thus guarantees unbalanced feeding. Keep a small slow swing in pH.
I had so much to do before leaving for a few days that I wanted to at least give them something since they had roots going. I'll transplant when I get back.
