If I start lollipop this will it stunt it or shoul...

Don't lillipop Autos and you only do it when the SCROG net is full and the bottom bits are getting no light and restricting airflow. Your plant is no where close to needing anything like that.

Your plants are only young and not very tall. At this point it's not called lollypopping until it's a mighty bush and then turn it into a lollypop shape like we do with apple trees to get all the energy to the top of the plant and not waste it growing fluff, at your stagehere now take the leaves off that are touching the soil so they don't mold up and watch her grow and minipulate accordingly, don't go around cutting tips or fingers off leaves your asking for trouble, sitting on the fence cutting leaves in half is ridiculous, either commit or don't but leaves are over rated lol to a point, is your not growing outside normal rules don't apply, whatever you get told. The basics are still there but threw minipulation the plants thrives better than left to it's own understanding, outside thinking not inside savvy..

you can take some of the low, low stuff off just to incentivize more upward growth if you want from a hormonal lever's perspective you are asking this but i see some fairly clean clean topping being conducted? is this an ad for your topping

I see no need to cut anything off the plant if the leaves were a little droopy or you didn’t have room with a lot of plants you cld cut the tips off the large leaves but all your new growth is not being blocked by leaves so your good
