Shinsimillathis is a leave from it thanks

Aah, I was hoping for a picture of the plant with normal colours, not just a leaf, but thanks. You might be a bit low on phosphorus, that you can up with no problem. It also looks a bit low in N and Mg, but adding a lot of that in flower is not a good idea, so give very low doses of that just so it doesn't become a problem. If you have any other questions about that plant, don't pluck leaves, just use a flash and it should overpower the blurple light.
