It looks like a lot of spacing between buds there, and not a huge canopy? I can't see the whole thing but that's how it looks to me from those pictures. Personally I'd keep them, they'll add at least a few grams to your final weight. It sucks to trim them when they're really small but every little bit helps IMO. There's been a few of my grows that I had nothing but small, larfy buds but it came out good so it got smoked. Really personal preference there. If you leave them, you keep your yields. If you remove them, the rest of the buds will get bigger but it may not increase yields, it may actually decrease them a little. You just have to weigh the pros and cons and decide for yourself. Hope that helps
