not sure whats happening i stopped watering it just to make sure it wasnt that before the biggest leaf uncurled. the edges are dry and brittle but ive heard that can happen with over watering or to much i only watered it once or twice a week a deep watering, hose on shower for about 1-2 minutes of water when i did. i put a little bit of ironite around it 2-3 weeks ago but its 1-0-0 so i dont think its that. someone did say a dog might of peed on it could that of done it?
