Hello fellow grower, looks like the light distance is absolutely perfect to me so far. Typically about 18-24 inches with those meizhis is ideal. Your distance seems spot on to me. The distance between nodes seem well structured and well spaced. I would keep the distance the same for now and slightly increase the light as she grows once a week. Solid genetics outta sweet seeds. Didn't know they had a cbd strain. Had a cream mandarine fro sweet seed a couple grows ago that looked like yours a bit and knocked my socks off. Might give yours a try one day if shipping from Spain wasn't such a hassle like last time. Keep up they great work. She looks strong.
Happy growing!
Stay medicated👊👍🙌
