I’m completely new to growing, this is my first plant. So just some background, sorry if it’s a bit of a long read. This plant grew from a seed i threw in a small pot filled with old soil that had been sitting in my garden. About 4 weeks after it sprouted i came home to find it had been blown over and half of its soil spilled on the floor, the roots at the top were exposed to the elements and it was still being battered by the wind. I set up a budget grow tent inside with a cheap full spectrum LED for when the weather wasn’t suitable and to extend the hours of light my plant received after i was told that the winter day/night cycle wasn’t going to cut it. Anyway my plant bounced back and is looking healthy except for these yellow spots on one of the leaves. Can anyone advise whether these spots may have been caused by stress or if i’m dealing with a nutrient or fungal problem?
