Hey there BigBucket, sorry but i gotta disagree about the leaf septoria , that's because of the way the leafs are yellowing towards the bottoms evenly,the way the leafs are yellowing towards the top in that splotchy way, and the way some leafs are yellowing at the serrated edges. Im quite sure you have a range of deficiencies. This is not your fault but basically such genetics need a lot of extra juice in flowering versus vegetation. You need to add more NPK across the board as well as calmag. Do this and the problem will stop spreading almost immediately and the plant will fully recover within 10 days. Hope this helps ! 🚀
