I think your just being impatient lol the buds are going to fatten up still based on what i see you have 1-2 weeks left of flowering maybe a bit more they will start to fatten up anytime now I imagine . I would consider getting prepared for your flush as you've pumped it with lots and lots of nutrients you wouldn't wanna leave that taste behind after all this hard work . IF after this harvest you're not satisfied with how your buds have fattened up you can also use products such as Bud Ignitor , Big Bud , Overdrive , these products used in combination will give you a massive yield ! You don't have to use those exact ones but you products similar to them will work great as well ! You may also wanna consider products like B52 a chelation agent that will help your plant rebuld stronger and faster because it acts like a protein shake for your plants muscles , Voodoo Juice and Piranha these both have individual benefits to them but mainly it would be for root mass and nutrient uptake , the bigger the root the bigger the fruit or in this case flowers ! Again you don't have to use these exact products there are many nutrient line ups out there that will do the exact same jobs . So when it comes time for you to select one be patient and select one that suits your needs and goals . You may also want to consider a way of training your plants next time in order to open her up to more light for better yield . You can do it a variety of ways so its best to look up the different methods you can try . You can LST , HST , Top , Fim , there are a variety to choose from . It's important to do your research on the method first so you don't do it wrong and stress your plants out even more leading to slow growth or stunts in growth all together . Over all I'd say your in excellent shape and well on your way to getting some tasty medicine ! Patience is key in gardening ! I hope this information has helped you understand you're options in obtaining your grow goals ! -Happy Growing!
