I run my lights about 16 hours a day and do make sure it is overnight and into the morning, when it is coolest in my garage. Cool temps for plants will definitely slow the growth. Mine typically take 2 months from seed to plant out and folks that work in warmer temps consistently have shorter times to get plants to a good transplant size. If you have a gradual warming in the Spring, I think that your temps are fine. If it stays near those temps consistently, that is probably a bit too cool.
