THC Bomb Auto Flowering

I changed out some soil in the pot. I ph’d the soil to 6.8 and then dumped two gallons of 6.5 tap water through the pot for three days in a row. I received some good advice regarding this plant. The decline started when the plant started receiving less sunshine. I raised her up so she could get more hours of direct sunshine. She seems happier since the flushing, soil change and more hours of direct sun. I am considering bringing her in under a plant light for some extra hours. I don’t have an indoor set up so I am trying to sort this out. She stopped making hairs on the buds and possibly revegged a bit a few weeks back. There is more green now after I recharged the pot with new soil. I think if I can get the sunshine goes increased she will do better. Also when I re-tied her back down, the top of her main stem broke (inside the stem only). The stem only broke inside the walls around are still intact. I suspect a knot will form now but it is Another stress to delay things a bit. People do this on purpose to their plants in veg. So I continue to ride this out and research about growing😃
