I need help determining what's wrong with my plants. I have 2 grand daddy purple plants and they seem to be going through some sort of issue. The leaves have these spots on them, and I can't tell what's wrong. Im growing in coco and using a 600 watt mh lamp. Im using reverse osmosis water and have a ppm meter reading at 730 ppm and I have a ph meter reading at 6.8.im using sensi grow ph perfect solution part a and b. Ive also added pennies to my storage water along with Epsom salt. Im also using liquid co2 and have used worm castings to make tea. For the life of me I can't tell why my plants have these spots on them. Can someone please help me figure out what these spots are?
