GSC Auto, My First Grow

Leaves have been drooping and a lot of stems have gotten red/purple. After researching a bit, I understand this can be stress from various things. I highly doubted it was over or under watering because I was very cautious on this from previous issues. I had been monitoring the humidity and temperatures closely. It has been getting quite cold in the mornings, and warm during the day, combined with very low humidity, sometimes as low as 22%. I decided that it's likely the erratic temperature fluctuation and low humidity was likely the issue. These have picked up over the past couple of days, I have noticed the plant has too. With all that said, she has actually grown quite well. Bud nodes developing nicely and main stems growing taller day by day. Thanks for stopping by 🙂
