What is growing on my GSP

[Islander722]

Good evening everyone!

I have some of this white filament growing on my GSP Frag and am not sure what it may be. Any ideas?

Thank you!

hmm hard to tell but my guess would be a sponge. Are you able tell if it's soft/hard to the touch?

Hard to tell from the photo. I worry about the tissue/encrusting of your gsp. The tissue is supposed to be purple. The lower portion, yours is purple and healthy while the top section is browing. Make sure there is enough flow on it. As the gsp creeps up the wall, the light may start to burn it.
