Hi I’m new here. I’ve been growing for about a year. I grow in soil, use cutting edge nutrients, and a 600 watt light on 18/6. My plants are growing fast and look great but the stem is normal for the first few inches then doubles in width and grows hollow like bamboo. There is no pith inside. It only happens when I grow from seed. If I grow clones they grow woody throughout. These girls are about three weeks and are already showing the problem
