"Monster cropped" clones can be 2- 4 weeks before normal growth begins to kick in again and I guess you could give it 24/0 but I don't think its a great idea r a cutting trying to survive: at least any cloning guide will not advocate for it.
I'd stick with 18/6 - some wheels don't need reinventing.
Also watch for the reason they call it monster - I have a Hulkberry I cut as a monster crop 6 weeks ago, in a week when I flip it will take half my 4x4 easy.
Growth will come from everywhere.
Good luck.
