Hello,

I have noticed brown color on the 1st top terminal shoot and the 2 fan leaves right under, the rest of the plant is healthy and good Pictures attached.

Is this:
- Boron Deficiency?
- Light Burn?
- What could be if none of the above?
- How can be treated?

I was planning to turn to flowering very soon, now i should reconsider based on the solution.


Thank you all

Yes, light burn.......back it off

If light burn do you think the terminal will recover, if light is backed off?
PS. i am seeing the same symptoms on 2 other crops

Burned/dead spots won't recover.
