if you have sexed them already then i would say NO just take what you get, if you do nto see a sex yet then i mean i personally wouldn;t unless thy were really cramped but its up to you to decide, look at what you have now
1. you have a healthy plant growing and flowering
2. you can actualyl get bud off of this
If you flower you have a few options:
1. You can kill the plants or hermi them (not good)
2. You can allow the plants to grow bigger thus producing more bud

Weigh your options, it's your bud
