Haven’t We Been Here Before?

So after our plants came back from their first downturn and started looking good and healthy again, they have once again begun to wild and deteriorate.  We checked the pH and temperature and they are both still at optimal levels for plant growth.  In an effort to turn around the problems with plant health, we increased slightly the amount of water the system has been receiving.  Instead of once every hour the plants are watered three times every two hours.  Hopefully this improves the health of our system.
