Hi y'all. Current caregiver, been growing for almost 20 years. So my question is My flower room is going into week 7 and my buds are not growing they seemed to have just stopped or just way to slow to develop. The look they should be at week 2. These strains I've grown before and this round is all cuts I took. What would cause the buds to not grow or to just stop growing? Room has 6 Fluence bioengineering spydrx and spyder2i. Temps are running 74-78 humidity is 50%. I have good airflow. Nute line is Canna and Mammoth. No issue with ph run off numbers. What could be the issue? Thank you for reading
