Brother your plants look great. Your at week 11 so to lose a few older fan leaves is natural. you can just remove the discolored ones they did their job. They are usually drained of nitrogen by this time. The brown part looks like a lack of calcium in the leaves. The rest of the plant looks fine. If possible you should start adding some extra cal/mag to your feedings when budding begins they will start drawing it from the leaves as they grow and bulk up. Hope this puts your mind to rest. Good luck
