GMSgrowsanswered grow question 3 years ago Are you in coco? I see your feeding canna coco. At the rate it says your feeding, that's way too high. If your growing in coco you should be feeding by ph and ec levels and they should be checked periodically after you feed or water, by checking the runoff water.
If it's a photo plant then 800 ppm is your max feed in coco. If their autos you stop increasing the feed when they hit 600 ppm. Your ph in veg should be set at 5.8 and in flower, when they start to flower, at 6.2 or 6.3
