Your plant is just pulling the nutrients from the leafs to feed her buds it’s very normal thing in flower if u want to up the nutrient level that would be good and I would add a lil more nitrogen and Calcium magnesium to the bloom nutrients but don’t worry at all she will be just fine looks good
The is a strain from Barney farm seeds the plant is 16weeks out and on it 3rd week of flower fun plant to grow looks like it going to yield nicely the plant is 68in tall and over that wide
