Help, too much leaf rot

[nunogdias]

I bought this Pinguicula 'Tina' maybe a couple of weeks ago from a local nursery. It has been sitting close to a window in a north facing side of the house, but without direct sunlight. I keep the substrate always moist. There is a lot of air circulation as the window is kept always open.

It started losing leaves to rot growing from the edges. At first I thought this was because of the humid substrate bulging out of the pot rim, so I removed some so it wouldn't touch the leaves. In the meantime I cut 2 leaves to try propagation. But now the rot is expanding faster and to younger leaves that are not even touching the substrate. It is putting out leaves and flowers at a fast pace, but I'm starting to fear the rot will outpace new leaf growth.

Temperature is currently above 25ºC during the day, so it's quite hot.

Is this a fungal infection? I sprayed fungicide today just in case.

Would more light help avoid this? Should I move it to a location where it gets direct sunlight until 9-10 AM?

Any help is appreciated.

It might be that it's too wet.  I've found my Pinguiculas grow best in very well draining substrate and standing on wet capillary matting in just a few millimetres of water.

Hope this helps.
