What do these patches mean? What am I missing?

I have been keeping 3 bunches of Windelov Java Fern in a small quarantine bowl by a window for weeks. I dosed a little bit of flourish once a week and with some aquarium water. They appeared to be fine.

A few days ago I moved them into a 3 gallon fishless aquarium with other plants (anubias, marimos) and all of a sudden they started developing dark patches of green/brown that are slightly transparent (some with holes). I was dosing flourish every other day. No CO2, No excel.

Thanks.

This is common in Java Fern species. It is due to low nitrates. Cut-off the discoloured leaves and increase the nitrates and no more brown patches ;).

Best Regards,

Stuart

Thanks Stuart. So I guess it is because I didn't have any fish in the tank for the first few days.

Thanks.
