30 days veg? they could be locked out, do you flush? how big is your pot? does it drain well? is the soil compacted? rootbound? just a few things to think about.

How tall a plant is, is no measure of how nice it is. It was 2.5 feet because it was not getting enough light and was stretching for it.
