The leaves turn yellow an a LOT of plants toward end of life. The plant is putting unused raw materials down into the soil, for the most part, and removing carbohydrates from the leaves. In hydro we help this along by stopping nutrient regimen two weeks before harvest, and give only pure water to allow the plant to consume itself, and the stored nutrients and carbohydrates in the tissues. If you are not doing this I suggest that you start with this current grow you have going right now.
Thanks for answering that Jandre! My plants have been on pure water now for almost a week. ONE more week to go and we will be pulling plants
