I'm entering week 8 and one of my three blue dream'atic autos is much more advanced versus the other 2 (see photos)
Buds are getting nice and sticky but in the past week, she's had some upper leaves around the main cola start getting brown spots, dried and crispy/brittle to the point where they crumble if I pinch them. The brown spots started appearing near the tip but not at the very tip, followed by general yellowing in the leaf area.
To try and solve, I did the following:

Big thanks for any insights!

To try and solve, I did the following:
- Flushed and fed again, adding cal mag because I suspected a possible deficiency
- Moved lights away to ~14 inches
General grow/plant conditions:
- The RH is between 45 - 52@ and temp is usually around 75-78, although it has gotten up to 81 on some days during late flower
- Lights (300w LED) are always 8-14 inches away and there are other colas on plants that are taller and show no burn issues
- I use FF trio nutrients and always pH my water (and added cal mag in the last feed because of suspected issue)
- I have two fans, one blowing (not too violently) over the canopy and one blowing under the canopy
- Trichomes on top buds are mix of clear and cloudy
- No insects or obvious signs of mold/mildew/bud rot
Big thanks for any insights!
