Shes 40 cm from bottom of the stem (pot not included). Yes light as high up as possible. I don't know if she's done stretching. I hope so lol. She's an auto plan and I read sometimes they stretch 40% during first week of flowering. She did stretch A LOT yesterday but today seems to be taking a break thank god lol i did some light definition yesterday and tied the top crown a bit down to the side. But still the main stem is much taller than he the rest of the branches. There is also a smaller branch at the bottom, which i think won't be carrying any bud, wondering if I should snip it off??
