So I was using coco coir for my auto-flowering cannabis plant. I don't think I overwatered it. So what do you think went wrong? Do you think it's a light burn because I kept it outside?

The plant eventually died. What I wanted to know is what do you guys think went wrong?

I believe there is no nutrients in coco, if using RO water in coco there is no nutrients available for the youngster. Ive only done a couple grows in coco as im getting out of dirt, if a more experienced coco grower would chime in would be great but i think you need to feed from day 1. N,P,K, and calmag.

I believe either diagnosis could be the problem but which one needs determined. Teldren has some good OG on NOTM right now, definitely knows how to grow the goods.You might have better luck adding 25% to 50% perlite to your mix. Mycorrhizae will help maintain healthy root zone as well. Check roots out. If not white then root rot could be the problem. We need to know if you were and what you were feeding as well. More info needed please.
