sounds like humidity? can you tell us what your temps, humidity and cfm of fan? filter?

If your duct has a low point where it sags down a bit or if its mounted in a V shape you're just allowing humidity and condensation to build up and it's all pooling in one location. Run your duct vertically or get a dehumidifier

i sorted it m8 there was an L shape in the duct and it was collecting there so i straightened it
