Critical purple auto outdoor

Tried an old grandma method of fertilizing ) with a carrot. Just tear the carrot and leave it in 1-2 liters of water for one day. Then the water becomes full of useful nutrition. No one knows what exactly there but it works fine with room flowers. Anyway I’m not going to use any artificial fertilizers the whole cycle. So we will see how it works with weed. Preflower start to appear. So it is an auto ) so happy it grew bigger than all my plants last 6 months
