I wouldn't cut the leaves the only time I would do that is if I was to take cuttings and even then I don't think I would do that , not that it would kill your plant or anything like that but it will indeed stress her out and make her focus her energy on healing that leaf instead of growing the way you want her to .
There's a few things you can do to gain new bud sites or even assure the one's you have are going to get big ! The first thing you can do is top them . This will encourage the growth of your plants to become more bushy . With that being said you will see that the internodes will shoot right up making more viable bud sites as well as 2 main cola's . If you chose this method you must wait atleast 1 week before you start to flower in order to give time to your plants to heal up properly !
Another thing you can do is when you're getting ready to start flowering you can book the PK of your babies this will encourage new bud sites as well as promote development to the current ones . There's a few good products out there that will do the job for that ( PK boost , Bud ignitor , Bud blood and the list continues) These products are all designed to facilitate the development of bud sites as well as bud formation !
You can also try the lollipop method but I would only do that if your bud sites were already plentiful this way you could even out your canopy to ensure maximum photon absorption and maximum bud growth .
All and all I'd say your doing well , I would just add some various nutes to help out your baby's ( start of flower: Bud Igniter , Voodoo Juice , B52 ) (Middle: Big Bud , Bud Candy , B52) (End: Bud Candy , B52 , Overdrive , Flawless Finish)
I hope this information helps you ! Keep up the good work !
-Happy Growing!
