Should I feed more ?

If anything you might be pushing a pinch much. Greenness of leave tell you how much nitrogen is in your plant. Too green and it claws. I would stick to current amount next week then if its starts to get lighter green by 2and week just a punch more. Feeding appropriate amounts and nutrition for size of plant is very important. In vegging your npk ratio is 3-1-2. In flowering it is 1-2-3. With autos you have to slowly transition from one to other as flowering goes on. Hope this helps and good luck. You are off to a awesome start. Happy growing 🌲🌲🌲👊
