Punctuation would be helpful on your part... It's nice to know where sentences begin and end in a paragraph. Just a tip for future posts as most won't reply to you.

Your plant is too young to worry about trimming the bottom branches. A week before bloom you can start to cut off some of the very low branches to stop popcorn buds forming later on.

Just let the plant do its thing in veg. I has some indicas that had a lot of tight branches like yours. It's just strain.

Take care
