If that's an indoor plant what light are you using? You will still need to cover up the rockwool so it doesn't get any light at all or you will have the same problem.
First try cutting off the top portion of the rockwool if you can get enough off and it has no algae you would be good with that. If you can't get the algae off then you will have to slit the rockwool in the middle and get the plant out. You might lose a root or 2 but as long as you have a root or 2 still on the plant it can survive.
