Don't cut anything off,
@seaecho. I am not quite sure what caused these fronds to have so many "blemishes". Did the plant have some sort of trauma what might have damaged its fronds?
Other than pretty small seedlings, I don't grow my staghorns in pots. I prefer to grow them as they do in nature, mounted. Keep in mind that these plants are epiphytes, and growing them terrestrially goes against their nature. That's just me, you understand. I also like the way their fronds drape off the mount. I have grown hundreds of staghorns, most of them the Platycerium bifurcatum (standard staghorn) and now the bifurcatum 'Netherlands' variety. Since you say yours is the "French Staghorn" aka "Silver Staghorn", you have the Platycerium lemoinei. I grow those as well as three other (rare) varities, Here are a few pictures of some of my mounted staghorns. The first two pictures show the "French Staghorn".
