Lollipop

Personally I would start to lollipop when she has begun to start her pre flower stretch..flowering is when you really want that canopy to open and allow sufficient light…Veg state is focusing on getting bushy so it’ll probably double in what you see in the photos in the next 3 weeks. During veg state I usually pluck those fat fan leaves that snap right off with a gentle push..if it’s fighting with you than leave it be. Good luck with your grow it looks great so far!

Looks like you have a stockier strain/Pheno so I would wait until you put them in bloom. Around week 2-3 of flower after they stretch.

I ussually do first bottom clearing when plant occupied all pot width and lsted branches start to grow up. Usually its around week 4 of veg. Then i do clearing weekly. Last one 3-4 days before flip. In flower better leave them alone till final strech is over, but if you need, bottoms you can clean almost any day. Always works better if you do it before watering, but i am soil man, you in other boat a bit ;)) Have fun !!!

Whenever you want. It just depends on when you intend on flowering the plants if you think about flowering soon I wouldnt stress them but if your going to flower in a few weeks go for it :). I tend to use Fimming more than topping myself as I find it an easy was to bush out plants :) Though each to thier own its your grow buddy your rules :) I would go for it the sooner you top the more time your plant has to recover and put the energy into healing. Best of luck buddy if you need any more help dont hesitiate to send me a dm im always happy to chat about growing :)
