How long left and when should I stop feeding?

Hey based on these pics, it looks like your light might be too close to the plant. It looks like your hairs are burnt a little bit on the tops. And for the timing it will depend on a macro pic of you can then you can see if your trichomes are cloudy. I would say still a few weeks for sure. Happy growing

Hello friend from the looks of it it looks like you need at least a couple more weeks. The white hairs on the buds need to turn a bit brown-ish color. Are you feeding any molasses or some overdrive? If not you should this fattens up your buds last couple of weeks. I wish you good luck! 🌱
