Hi
@DeeColorado! You don't want stretch, you want short internode spaces and a plant full of buds, instead of a stretchy tall plant with big stems and small buds... 24" seems already a pretty big distance, so I won't recommend to increase this distance for the moment, unless you see light-stress signs or heat troubles. Your plants look fine for 14 days, you're doing great! Keep us up-to-date, and happy growing 👊
