Need help ASAP,,, 29 days from seed, and my plants look small, for how long it has been, is this a normal size at day 29 from seed

Here's my current grow when I was at 28 days from starting the seeds. Those had been very recently topped. You're about at the point where they should start growing faster and faster.

I've attached what these plants are looking like in week 12 from seed, just for encouragement.

A little trick that can help is just don't check on them for a few days. If they're watered well and on auto pilot just let them be for about 3 days and when you check them again you'll be really happy with their progress. I was out of town a lot during this grow and was away for nearly a week twice. Seeing the new growth was amazing. I couldn't do that now though. I'm using the Earth Box system and they're taking about 2-1/2 gallons every 2nd or 3rd day.
