I agree. The easiest way to increase a vft's growth is to feed it regularly. You should aim for having one trap digesting prey at all times. You can amend that with 1/4 strength maxsea applied to the foliage with a cotton swab. Avoid getting the fertilizer solution on the soil since that could make its way to the roots and damage them in addition to encouraging carpet moss and other annoyances.
I'd avoid feeding your plants as they go into dormancy though. That's actually one way to avoid dormancy altogether. Not recommended for most growers.
Another way to stimulate growth is to repot annually in the early spring right before they break dormancy. Venus flytraps respond very strongly to fresh soil and will put on a flush of strong, large leaves as a result. You can tell a repotting is overdue when the plants are putting out lots of smaller leaves and are producing lots of bulb divisions instead of focusing their energy on large, beautiful traps.
Hope that helps!
