Is she ready to top? Where do I top?

Hello.. Hope you are well.. She looks nice and healthy.. Yes u can start ur high stress training and cut her at 4th node as u asked.. Technically u cud cut and leave as many or few nodes as u want.. Take her top as u mentioned then wen she fills out a bit if u wanted to u cud take away the very bottom branches if they dont grow as fast.. Stay safe n gud luck with her.. 👍🍀

Looks ready to be topped, perfect stage ;) Best of luck

When it comes to topping is a general preference I'm usually top at the 6th node because that will give me enough branches to Savage a decent crop but some others like it at the four node and extensive training to get a decent crap out of them so the more higher you do your topping the more branches you will have to work with in case not all of them develop as you wish but if you lack of space then you also want to cut them low to control their height when it comes to where to do it is just below the green leaves up the stem part below where the leaves are growing there is no right and wrong in fact if you do Miss it's called FIM and is it beneficial as well the most important thing is that the plant has to be healthy and she's going to have enough branches for you to have a decent crop unless you going to do a large vegetable growth then she will have enough months to grow lots more branches. hope this information helps you out good luck with your garden have a happy grow

For a shorter plant top at about the 3rd node! I always wait till my girls have at least 5 true nodes before I top. Your looks totally ready you can take it anywhere from the third to the very tip. It's just your preference on how high you want it to grow and what training techniques you plan on doing it with! Cheers and happy growing!
