Trouble reaching 25T

My income stalls out once I get up into the planets in the 30s. More specifically I can’t seem to unlock planet #37 Ultritus (25T) within the time of a single tournament.

Maybe I’m not focusing enough on certain rooms in the mothership? I’ve been trying to open as many new rooms as I can while still balancing across most rooms.

Any advice on how to get over the hump is very much appreciated!
