Yep definitely time for a res change i think!! Dump the old water, give container a wipe out with a wet cloth, try and run a bit of water through roots. Then simply fill back up add nutes to desired ppm (in my experience, always less than what the manufacturer recommends) and adjust ph. Monitor ppm and ph everyday and adjust accordingly. Most people do a res change roughly every 10 days give or take.
