I was on a roll with first-time grower mistakes this week! Know better, do better!
1. I managed to hit Plant #1 when I was adjusting the fan and knocked it over. I replanted it in its pot and didn't see any damage. It was leaning but I didn't want to rebury it too deep or pack the soil too tightly.
2. There is purple on the branches of both plants, and I think it is "tannning" because of the light. It's only on the upper half of the branches, so after reading the light's instructions, I'm raising the light up to 18" and lowering the intensity to 60%.
3. After researching what I'd need to setup up carbon filter-wise, I noticed that I had a lot of negative pressure in my tent. This was because I didn't have any intake holes/flaps open. I opened the back intake panel on the tent and had significant airflow improvement. This is going to allow light into the tent during "nighttime" but since these girls are auto-flowers and the amount of light will be minimal, I'm not worried.
