Well last week i put some plants in my tank and they were pearling away. i have good light and co2. Now all of a sudden my plants stopped pearling, no algae. I noticed my Erio's were showing white growth, maybe be micro deficiency. So i dose a lot of micro's to make sure the plant has plenty of uptake... but no pearling in any plant (Even ones without deficiency still. So i turn off the lights dose macros and wait 2 hours. Turn lights back on wait for 45 minutes (They used to pearl in 15) and NO PEARLING. this leads me to believe that organics are either breaking down and consuming N and Oxygen or that my plants are still deficient in something. Any ideas?
