Thanks Ed, kit1212, Wong and Shamrock, most of my neps are still young, hope they'll be even beautiful when they reach maturity.

kit1212,
I just started using seaweed based fertilizer via foliar spray. I used to apply fertilizer into the pot to fertilize the root zone but I don't like the eventual development of blue green algae slime overtaking the LSM.

Whenever I repot I always add some slow release type fertilizer like Osmocote. So far, I haven't encouter any side effect with the application of slow release fertilizers.
