Hey it looks like nitrogen deficiency. Buds are taking nitrogen from the leaves and not the soil. Hope this helps happy growing.

Another thing to look at is where/what. Where/What leaves are affected. Old/bottom or new/top. My guess is N, P, and K, unless you have re potted recently.

Yellowing leafs and dying tips
Hello ! In the last few days I founded that some leaf started to yellowing and burning on the tips . Maybe it's all due to the flowering stage but I'll be more calm with your answers that are always interesting and helpful even if the platform allows only one to be selected.

Lower leaves turning yellow and getting crispy
Lower leaves are still turning yellow/brown. See photo. A couple weeks ago I got a greenhouse to protect the plant from the rain. Outside temperature has been lower and there hasn't been much sun (mostly clouds) so I don't think heat is a problem anymore. Don't know the pH. Help!
