pinching tops to young ones ?

okay my clones are well growing and i started the count from the moment they started to show growth development now i would like to manipulate the little ones by pinching the tops and make it bushi many tops , my question is should i wait a little bit more like few days till i try the first top pinching or should i wait longer , good advise is welcome thank u worldwide farmers !

Wait till they are at the 5th true node so that way they can recover quicker and are all established.

If you wait until they reach 7 nodes then take off the very bottom set of limbs, then top her down so there is 4 limbs, you will have a 4 top start then you fim each top 1 week later for a 9-12 tops.

I go by uncle bens topping technique for 4 main colas proven and tested method always works.
