What is up with my Rotala?
I have quite a bit of Rotala in my 20 gallon awuarium.
I have Exo complete as the substrate, I dose Iron, Potassium, and nitrogen, I put in DIY Osmocote root tabs in the substrate, I am running a 100 watt 5000k CFL light, and I am running DIY co2. Simce a couple weeka ago, I noticed the top maybe 3 or so inches of many Rotala stems not leaces are turning black.
There is new growth on almostball of the Rotala stems.
Why is this happenning?
How can I stop it and make it better?
