Buds not fattening

Hey gardener! It happens all the time that the pistils turn orange while the plant can still grow, and just because some turn orange doesn't mean the plant is ready. In fact, it can start making white pistils again in the same spot where they turned orange. It could also be because of the cow manure, which must be pretty strong to trigger a reaction like that due to its NPK. Since you went from nothing to this, the plant might have been shocked. Otherwise, get ready because they’re all going to look like that soon. Good luck to you, bella ciao!

i would give it some time.. something that's controversial, but you could try is called "pinching buds" or "back building".. here's a link explaining what it does and how: https://www.420magazine.com/community/threads/las-quick-guide-to-simple-backbuilding-technique-for-buds.209274/ some may disagree with this procedure though..
