Buds not fattening

Hey gardener! When your pot is small, you have to fertilize hard! Give the maximum dose or almost at each watering because with 5L the plant quickly absorbs the nutrients. You can tell she needs it since she's light green. Good luck to you, bella ciao!

Some strains won't double until the last 2 weeks.

Hi buddy don't worry first :-) How high is your Ph value, how high is your Ec value and how is it watering behavior and interval? :-)

Hey Johnny!!!! Depending on the NPK values you've been giving your plant, it looks normal. Time is everything, my brother! If the problem persists, increase the PK; otherwise, lay back and let them fill out on their own. These are my 2 cents for you. Take care! ;)

Hi there! It might be normal for this plant 'cos every girl grows on their own schedule and bud fattening happens in the middle of the flower. When I look at your girl she has some yellowing on the lower leaves which tell me she wants nitrogen and it is also needed during flowering but not so much than in veg. Maybe you could add a bit more nutrients overall and see hos she reacts? What is your pH and are you sure you don't have any lock outs etc? Adding nutes is the simple answer but if there is something else wrong it could make things worse.
