Hydro Drip Question

Hello guys I recently got a new pump for my hydro drip set up and noticed that the 365 pump moved a lot more water than my old 66. My question is that the water seems to move really fast through the drip lines into my rockwool cubes. It is more of a stream than a drip I water to times a day for 15 min my seeds just sprouted. I would appreciate any help I can get is there a way to slow down the water?

Hi. Might help might not.

I made my own drip system, but it acts more like a self watering system.
I am growing in perlight only, and water for 2 mins once a day.
