yeah, that's exactly it. My brother-in-law always said it was "something in the soil", but you seem to be using potting soil, so I'll rule that out not that I thought it was the soil anyway, lol. There are literally hundreds of viruses and fungus that affect cannabis, I just wish I knew exactly what it is. Helps to know I'm not the only one here that has had the problem. I'll keep spraying with neem oil, damage control. I've seen it destroy entire plants from top to bottom.
