Beginner help needed :)

Hello, in my opinion I would let she grows more 1 or 2 nodes and then start training I prefer to lst a little late that doing soon and she not handle it. For lights if you want to save try 100 watts or use a led lights you can find some cheap lights (but not to reliable in relation with watts) on the AliExpress for example, or for a more accurated watts you can buy on amazon but they are more expensive. Hope it help you! Good grow! ✌️🏼
