Leaf tip curling up and yellowing

I must agree with my fellow growers. Looks like you need to increase your nutrients just a little bit. The vast majority of your plants look great! Nice green and healthy. Your problem isn’t a big one, and a lot of leaves start turning yellow toward the end anyway. So your choices are easy, increase feeding/nutrients, or do nothing at all and let her be. She’s going to be fine either way. To help make the decision easier, think of how much time you have left till harvest? If it is more than a few weeks, and buds are still fattening up, then increase your feeding a bit. If it’s just a week or two, then maybe you can start the flush to get ready to harvest your bud. Either way, I believe you’re going to be fine. Happy growing!

Just like @Papa_T said - they are big girls and will be hungry in their final weeks of flower, they will be stripping themselves of nutrients - might be time to increase your feeds if they are still receptive, if not just start flushing and ride it out.

I would say that they are pulling everything they can because the soil is finished. (good timing) you gonna have sweet smoke!

Hey man!! Sup!! No they’re probably just a bit hungry at this point if the food isn’t in the soil they’ll start eating fan leaves. The plants are consuming the fan leaves to make you danker bigger bud. The bad one I just en up defoliating and just let it happen. All the buds look wicked right? So no problem. Fan leaves are not the prize. 🤣 No stress brother you got this.

I’m growing outside.

Light to close or to hot.
