I have a six week old Purple Punch autoflower that I transplanted into the ground outside at about the 4th week. I'm noticing the pistils are turning very dark especially the main cola. It's planted directly in soil supplemented with compost/manure. I have another one of same variety and age growing indoors that is normal. This is my first grow outdoors with this strain so not sure what's going on. Using Fox Farm Cultivation Nation Flower fertilize and supplemented with Fox Farm Grow Big every other watering. The weather has been in the 90's and dry for the last few days. Watering only when soil is dry. Please see attached pictures and thanks in advanced.
