Why is my BTA so stretched?

Reduce the flow over it. After a few weeks it'll bubble back up

I have a about 3 or 4 bubble tips and the ones getting the most flow have the biggest bubbles and the ones below are stringy. I have found when I add more flow the bubbles come back.

Ive found the exact opposite of this with mine. Too much flow and they get stringy. No flow and they bubble up.
