Are these your best pictures? Because I don’t see anything wrong with them other than the tips. But so you know Coco has no nutrients whatsoever, so you Do have to manually add from a vast selection. At the very least Something like Advanced Nutrients Sensi Grow A&B for Veg what with being an auto is very short “21 to 30 days” & Sensi Bloom A&B for Flower with will start from the end of Veg until typically about roughly 70 days with an auto.
