Hey Everyone,

I am having an issue with some of my plants. I have used the same nutes for a while now (H&G) and I have never had this happen. I following the same feeding schedule and these are the same genetics as all my previous grows. Unless my PH meter is having issues I am watering at 5.8 ph in coco. When I test ph run off I am at 6.1-6.2. From researching it looks like possible PH issues or maybe Mg? Has anyone experienced this?

Thanks!!
