I have nute burn on most of the sugar leaves with about 3 or 4 weeks left until harvest.Will my buds continue to swell with this kind of damage...I did a flush and feeding ph water
Yes they will continue to swell , if you have done a flush then the burnt should stop spreading and the plant will have enough leaves to acheive photosyntesis. As long as the leaves are only 20% damaged like yours you'll not notice a change ( or a tiny one )
Only root rot could stop your girls right now! They will slow down because of the nute burn but if you've already started flushing....you should be good tp finish with a decent weight!
