Autoflower PPM ?

Start babies at 400 ppm 0.8 ec.for both coco and dwc. Next week 500, 1.0 ec next week 600, 1.2 ec next week 700, 1.4 ec next week 800, 1.6 ec That should be as high as you need to go. Feeding schedules. Dwc always has those amounts, coco feed, feed, feed, water etc. If ec starts building up in the coco then more water. Ph through veg for both is 5.5 to 6.0, 5.8 being optimal. In flower 6.0 to 6.5 with 6.2, 6.3 being optimal. Always check your runoff ph and ec levels to make sure your staying in the proper levels. A little high ec coming out is ok but dont let it get to high. Cheers friend
