If by "fingers" you mean those outer 9 tall colas, then yes. During veg, as they grow taller, you keep them tied down flat until the inner smaller colas grow and catch up. Once they’re all almost even, you switch to flower. You’re already 3 weeks into flower, so it may be too late to start doing it at this time because those stalks are probably hard and woody by now and you'll risk breaking them and causing too much stress. You can supercrop them, but that will stress them out as well and delay the growth a bit. But just ride this one out. She’s healthy and looks good. You can try it on your next growth.
