She isn't growing as fast and strong as the others, but I will see, I transplanted her into a 21L pot filled with 3/4 coco, I do not know how to grow in it but I wanted to try it ! We'll see how it goes! I guess I gotta water it more often, and probably put some nutrients as it's not as rich as soil.
ps : sorry for the poor quality of the photo, the sun was on the wrong side and I could not turn, I'll do better ones :p
@Weedseedsexpress, It really is okay, the problem is the medium, but she is already very stressed and started preflowering so I am not going to repot her, and I already gave some N. Thank you for stopping by, sorry for this grow^^
@FR_PhenoFinder, don't know if you pin pointed the problem already, if not, I'd recommend reading the following blog: https://www.growweedeasy.com/why-cannabis-leaves-yellow
