Leaves curling down

Any form of downwards curling usually indicates overwatering or overfeeding. So if your not overwatering, it'd overfeeding my friend. Hopefully, I answered your question and remember " Happy Growing and Free your mind one puff at a time ".

Honestly, it looks like too much nutrients. In organic soil, particularly for auto flowers, you shouldn't need much if any additional nutes, and a light dose of compost tea once a week should be fine. For veg, a tea of straight worm castings is fine, and for bloom a guano tea is great. Organic soil has microbes in it to turn these organic substances into the nutrients your lady needs, and any artificial nutes run the possibility of killing them and defeating the purpose of organic soil, and also will likely cause root burn.
