How soon to top clones?

Hey guys and gals, thanks you all so very much for the wealth of info you all provide to me and others. For the most part I have been able to find answers to all my questions through previous posts but I have a question now I can not find an answer to, searching here or google.

I have some clones that are decently rooted in rockwool. I have transplanted them into some nice organic soil. Now considering that they are already the right height, how long do you think they need to be in the soil until I should top them?

Does it need to have a firmly established root system in the soil before I should top?

Or can I top right after transplanting?

Dont want to kill my babys!!!!

Much love and thanks to anyone who can help shed a little light on the situation.
If this has been covered before I apologize, but I did do a rather extensive search that yielded no results on my end.

Peace and
long live 215

I usually wait to top my clones until after they have shown sign of new growth. Generally after I transplant it take about a week until they all green and perk up, then those first new set of leaves come out, thats when I top.

Thanks alot for the reply!

Any other thoughts on this?
