Yes they are looking very nice...

Time to take down the next set above it. That will expose the highest secondaries you have. Those will produce the biggest and best buds as well.

So time to get them exposed.

I notice all your other plants are taller but notice how they dont have the secondary branching going on other than stem and leaf top?

Also, your sex has now been determined so you want to check every day for pre-flowers. Your environment is ripe for them so start check every node on the main stems.

Pre-flowers can be hard to see until they grow bigger, but you will know them when you see them.

Be on the look out.
