Jef79answered grow question 5 years ago Hello.. Hope you are well.. At sum point did they overfeed a a small amount and then uve gave them gud flush and then held bk a bit on nutes.. If this is wots happened then u dud the right thing at the right time n saved them alot if stress.. I also find that if u switch to ur bloom feeds to soon b4 flowers appear then she will lack the nitrogen to keep her leaves glossy all way thru.. Either way they look great and the yellow leaves are paleing because they have uesd up all their energy and shes getting ready to harvest.. Kinda like autumn leaves on a tree loose color..if she has had a constant gentle breeze around her buds then its very little chances of bud rot tbh.. Stay safe n gud luck at harvest.. 👍🍀
