Hi Guys, some of my leaves are developing a purple shine. I guess its because of a nutrient deficiency but im not 100% sure. Im watering every week once with 0,4-0,5ml of Bio Grow. What should I do now?

Because you have been growing in soil you have done the correct thing with giving only a slight amount of nutrients. Also with it being an auto they don't feed alot. The shiny leaves are from a build up of nitrogen. The plant like nitrogen in veg. She is now going into flower so you want to start adding a bloom nutrient. You have nothing to worry about. When you go with bloom nute start at half strength of manufacturers recommendations.

Your plant is in pre-flower and now is the time to start adding bloom nutes and to cut back on the grow nutes. I worry about the PH levels and wonder if you've checked the level of your runoff? It needs to be between 6.0 and 6.5 for proper growth/absorption of nutes... Check out any of my diaries, if you want, as I only grow autoflowers... Good luck!
