I have this Clusterfunk plant in straight coco that is showing signs of a possible deficiency. I am leaning towards calcium. It is watered with Dyna group at 7grams per gallon with filtered water not RO. Here are pics. Any ideas are welcome.
Have you foliar fed anything? Any chance you could have spilled some nutrient solution on the leaves when watering? Splotches like these can show upon my room after an IPM treatment. Bham Sent from my iPhone using Grasscity Forum
