any advice?

I just looked through your diary, seems like it didnt get enough or the right nutrients as well as soil space in the first 4 weeks. Its came back a long way honestly and looks good. You mentioned in your diary struggling with heat, which is something I can relate to. Check your VPD, there is a good vpd chart on the spiderfarmer website you can follow along with. Proper temperature and humidity relationship is essential for the plants photosynthesis process. Check out this page and it should explain it better. https://www.spider-farmer.com/blog/vpd-chart-in-celsius-and-fahrenheit/ Ive been in the same situation and relating the the vpd chart was a game changer for me. Sometimes i have to keep upwards of 60% humidity in there to keep it in the vpd range, because of the heat. Swamp coolers are your friend. Hope this helps
