I drained the system and flushed it out with bleach (with plants out). Everything's starting to look better. Sitting at 1.0 EC and 5.8 pH. The bulb is 24" from the plants.
That's true. It was brand new for this grow though and the only smells were coming from the reservoir. A flush and res change seemed to clear it up.The other possible thing is the AC unit. After all it does collect moisture..
