I was just wondering if you could top your plant with pistils?
If you have pistils at the tips of the plant then leave it alone to do its thing. If it is pistils on calyxes at the nodes, then you can still top it. If pistils are on the nodes of an auto, then leave it alone as it is about to flower.
No, that would not be a good idea
To answer your question as ask, “could you top your plant with pistols”?
The answer is Yes! Yes you can.
But it’s best to do it before it’s in flower, plants get pistols when they hit maturity and thats way before flower.
And even once in full flower or at any point, you most certainly can “top” them but theres rarely a situation where it would be beneficial to top once a plant is in flower…
If you have a plant you was thinking of topping, if you show us a picture of it we can give more accurate advice on if it a good idea or not
