Buds not fattening week 9

Still have lots of time. The preflowers will grow out a bit, then does this stage that seems like doing nothing just a few hairs here n there. Then the hairs will start to turn color, and the buds will go into a doubling phase where they fill out and have mix of amber and white hairs, once all hairs start turning amber is when you'll want to start flushing and looking at the tricomes

Insufficient lighting, shitty environment, not knowing proper growing procedures, lots of factors like Norcal says. Cheers

Not seeing a pic or a diary. There could be so many factors my friend. Any extra info you can include?? I'd love to help!!
