well easy solution, get a bucket add water them from the bottom
in your next grow rise your lights to 70 cm, then the plant stretches more to the light, and cut the lower branches 7- 10 cm above the surface
of the soil

Thanks, I'll try that at the next watering. Or can I do it now?
They haven't grown because I cut the main stem way too early. Next time, I won't touch anything.
