Talk about a contested topic. All the old skool guys from the 70s,the books I first read say only remove some of the bottom canopy,lollypopping to help with air flow but Kyle Kushman started writing for soft secrets 15ytrs ago saying strip the majority of leaves off your plant, and when its in flower of all times. Jorge cerventes must of gone insane when he first read that, the author of the best selling grow book on the planet "the bible" they call it.He a guy from the 70s and talks about stress but they clearly do really well with it which is why I did my last one which finished 3wks ago. It looks pretty similar to yours but mine was much more indica with twice as many leaves and shorter internodes, distance between leaf sets where your buds start. Looks like youve only just swithed to flower. Looks like youve left it late as they're very tall. It looks very hybrid/sativa like and may stretch another foot once it enters flower. Make sure you've got enough height.
