Plants not flowering

Not exactly greenhouse but closest that made sense:

I'm growing some veggies in my basement, under grow lights. They're doing well overall - the plants are very healthy, but I'm having a few problems.

Cucumber: (variety Socrates) I'm getting a lot of small fruit, about 1" long, with flowers, but they don't get any bigger. I'm beginning to think I may not get any: variety is gynoecious, it was supposed to be self-fertilizing but maybe not? If that's not it, any suggestions on getting the fruit to grow?

Tomato: (variety BHN-589) No flowers, no buds for flowers. Maybe I just need to wait longer, but I thought I'd be seeing SOMETHING by now. I'm wondering if it might be a bit too cold? The pots are on heat mats but the air temp is pretty cool, probably around 65 maybe a bit less.

Pepper: (variety Sprinter) Same as the tomato, with the same questions.

I was a bit concerned about the Zucchini (Partenon) too - it set and dropped some really small ones, but it seems to have set a couple over the last couple days that are growing.

This is my first time doing anything inside like this so I'm not sure what I might be doing wrong.

My (very uneducated) guess would be air temperature and humidity. My unregulated inside humidity over here in Durham has been hovering around 30%. Maybe try a heated humidifier?
