Sour Kosher and Full Moon Flowering Problems

The grow
- organic soil
- humboldt nutrients
- Blackstar Led

-It appears to be a nutrient burn, but I haven't fed them any nutes in 2 weeks. It's happening on both plants, but more severely on the Full Moon.

- Seems to only affect lower leaves.

- Lots of fallen leaves on the Full Moon.

Looks real hungry. Why aren't you feeding them?

Mainly because it appears to be nutrient burn --> burnt tips. As I understand a nutrient deficiency is a yellowing of the leaf. What makes you say it needs more nutes?
