Lookin good Bro. You still have a lot of time left and they should fatten up a lot still on their own.
Hard to say what to do different since I don't know what you are doing and everything looks pretty good already. Looks like the plant in the background is having some issues by looking at some of the leaves.
If you give more info on your grow, folks can give you their advice, you can take it or leave it. I have found some great advice and help here so I advise to give it up and see what the experts say.
