Hi. One of my plants' lower pistils are sort of dying of (turning brown) at week 1 of flowering. The majority of them are white but it doesn't like they're developing at all. I did have a calmag def a week back as it started pre flowering. I'm not sure if that could have stunted it a bit. First 3 photos are the plant with the problem. I also added some photos of my other plant which is about 2 days younger and pistil development looks way better.
