It looks to me like you have some algae growing in the rockwool and your line feed is causing it to run into the rez. Some peroxide in the rez will get rid of the algae without draining and scrubbing it out. If you soak the rockwool with a dilute sol'n, 1-2%, of peroxide. Just mix the drug store 3% stuff 1 to 1 with water and wet the rockwool with it with the feed lines off and it will kill the algae without hurting the roots. Rinse with water after 10-20 min and re-apply.
If you cover the rockwool with some styrofoam or other light-blocking material it will help prevent the algae growth.
Your air-stone could be plugged with algae so I would replace it with a new one. Take the old one and soak it in bleach or peroxide to clean it up and it can be re-used. Your air pump could be underpowered or have a hole in the diaphragm reducing air flow. I'm not sure what pump you're using. I use a dual outlet pump rated for a 30 gal aquarium to run two 12" stones and the water bubbles great.
Hope that helps. +Rep to take the edge off your worries!
