m0useanswered grow question 1h ago Best to show is photos of the mold and said white worms. Might be able to distinguish it better and provide better advice.
Coir mold could just be mineral buildup. or maybe even beneficial fungus like Mycorrhizae
Worms idk. might be a good idea to water in some BTi as a prevenative.
Also what else is mixed into your medium...
Don't stop watering it, if it needs water give it some. Be aware of a wet and dry cycle.
