Was thinking if you are fermenting outside it could be getting colder than 68 in a temp controlled fridge.
Im no expert, but I dont think you have a starter issue. When I started I brewed a few beers with no starter at all. They didnt turn out so well, but there were no attenuation issues.

We used US-04 on a 9.5% Impy stout, and nailed our numbers perfectly, with an insane fermentation. We're not doing starters either. Rehydrate, cool to pitching temp, pitch. I started with dry yeast (like most people) when I first started brewing, then I went to liquid, now I'm back to dry. I started having attenuation issues with liquid yeasts--starters and all--as well. Just some food for thought.

Honestly I don't see any good reason to use liquid yeast unless you need a special strain for a Belgian, Hefeweizen, etc. Dry yeast like S-04 or S-05 provides a clean ester profile, is cheaper, higher cell count per pack, stores longer/better viability, and you don't have to plan ahead days in advance or mess around with starters. IME they also attenuate better and result in a more compact yeast cake/clearer beer.

Most do intermittent shaking. The nice thing about Mr malty is you can choose this method to determine the appropriate sized starter. I started with an aquarium pump then went to pure oxygen and now I finally got a stir plate to reduce the starter volume. It also reduces the need for stepped starters

this is a problem. no oxygen is being added because you capped it shut.

at least toss the wort back n forth among sanitized buckets a few times, until it gets foamy!

Or you could get a siphon sprayer to use when racking to the carboy. I used that before getting an oxygen system and it worked great without having to shake anything.

Sorry for the delay, weather and all you know.

I got all my stuff at Pets Smart. I got the smallest one they had and it works great. I spent less than $20 I think for Pump, tubing, air stones and valve. As sjbeerman pointed out, unless you get a flow control valve for the air tube you WILL have bubbles coming out of the flask.
