Is moving up in weight too quickly hurting my muscle growth?

I’m wondering if I’m increasing weight too aggressively in the gym. My goal is hypertrophy, and I know progressive overload is key. When I hit my rep target, I move up to the next dumbbell or machine weight, and my reps drop from \~10 to 6–7 which I know is a big part o me going again to the next weight..

But when do you stop?

I’ve started dropping the weight to do between 12 and 15 reps, maybe 5–10 kg lighter than what I can currently handle. I’ve started this within the past week.

Question: should I stick to my initial strategy or the new one for hypertrophy?
