Hi this is my first time growing ever. Planted one seed and took a shot. My plant is almost three months old and I recently brought it inside for 36 hours of darkness before 12/12. It's an outdoor plant and I have been using miracle grow moisture control and using regular water to water it with. Once I took it out of 36 hours of darkness there were brown spots on my leaves. Is his from foreign debris? Nute burning? Maybe heat stress ? Please someone help
