Might wanna check for light leaks.
Maybe add a cap full of hydrogen peroxide to help.

Yeah dude you have light leaks rockwool is a haven for algae I have even gotten it on rapid rooter plugs...try and wash the roots with water to get the algae off .. Just keep your reservoir 100% light proof and keep those reservoir temps under 68 degrees and you wont have a algae issue also cover your medium with something that doesnt allow light to penetrate through .
