Durban Poison Feminized ScrOG grow

End of week 5 of flowering and the leaves are definitely yellowing more than they should. When I looked closer I realized the center stem has started to split. Normally the plant lifts the screen up and it’s not a problem, but this grow I am using a small fan that is attached to the screen. I think it’s weight was just enough to keep the screen solidly in place. I have propped the screen up on blocks about 2 inches higher, it relieved some pressure. I zip tied and taped the stem, hopefully that will allow the plant to still get nutrients to the buds. This grow has been just one little thing after another and I don’t have high expectations. Thankfully I have a cutting that rooted and I can regrow these genetics. The smell is increasing some and is quite lovely!
