Switched my substrate last week and transferred my plants over. Was dosing the recommended PPS daily dose but started seeing a lot of algae so I cut back. Now all of my plants look like they have a reddish dust on them. The ludwigia especially is gone from red to almost dead and the broadleaf ludwigia looks like it's rusting and browning. Polygonum completely died in 2 days. Any ideas what's going on? I removed a lot of plants when I reshaped. Should I just cut out fertilizing for a while? The co2 cranked up to almost yellow on the indicator
