brown spot on Phalaenopsis

[blee026]

I have a large brown spot on a leaf of one of my phalaenopsis. Should I cut it off or leave it alone. Thanks for the advice!

The first picture is the front of the leaf, second is the back of it!

Based on my experience just cut it and apply the raw area with fungicide in order to avoid secondary infection dont keep the lesion there is abnormal tissue.

thank you very much, will do! Just sniped it off. After observing it, the backside of the second leaf is brown too and it seems to be on the backside of the third leaf
