Tissue cultured Microsorum Pteropus dying

[JayZH]

Got a pot of tissue culture Microsorum Pteropus 4 weeks ago, it is grown on a piece of "mat" thingy emersed agar. I cut the "mat" and superglued the bottom of mat to the driftwood.

However, one piece of it is turning dark and dying since last week. as circled in red, also I just noticed the Alternanthera reineckii 'Mini' next to it also starts melting, circled in yellow, also 2 leaves from a mature cryptocoryne wendtii also starts melting, all other plants are great.

I started dosing Tropica specialised ferts (contains ammonium, NO3 and po4) for the past 3 weeks. about 1.5 to 2ml everyday. otherwise, ph 6.5, kh 7 co2 30-40ppm. there is good water circulation, as the driftwood is directly place in the path of a wavemaker.

Any ideas on why? thanks in advance.

Poor CO2/flow/distribution.

They are all in the same area.
Co2

Hi Darren, I think what Clive is trying to say is that the reason these plants are suffering is because of poor flow in this area, and as such the plants that are suffering aren't getting access to their required levels of CO2. Might I suggest playing around with your filter outlet to achieve a more even flow around the whole aquarium? When this isn't possible due to large hardscape etc then I would suggest adding a powerhead to try and encourage some flow into the affected area.
