I got my Tennessee Burley growing fine 4.5 feet. I am growing indoors with about 12.5 hours of light on the plant day in day out. Is there something I need to do with the lighting to get the leaves to turn yellow so that they are ready to pick and start the curing process? Or do I just wait for it to happen naturally? Also as a Side question, with a 4.5 foot Tennessee burly plant growing, about how far am I away in weeks before it’s harvestable?
