What is going on? I have a light rust colored odorless gell oozing from my pcp furnace condensation pipe. What could this be? Should I be concerned?

Any input or suggestions would be greatly appreciated!

It is rusty water coming from the condensate pan , it may mean that the pan is very rusty and possibility of it not draining properly , it needs to be pitched to drain properly.Some times a gel will form in evaporator coils due to standing water and cold temperatures. Need to clean pan ,check pitch and yes it not good to grow things in your air stream.
