Yes, it's quite common for cannabis plants to develop yellow leaves during the later stages of flowering, especially around the 8-week mark. This can happen for a few reasons, many of which are normal and not necessarily a cause for concern.

Seedlings with yellowing leaf edges Any insight on what may be causing the yellow edges on these seedlings? I'm reusing FF Ocean Forest that I used on my last grow. I didn't amend the soil in these containers as I didn't expect they'd need anything before it was time to transplant. pH was good at last harvest.
