Hey guys just a quick question.
I'm day 36 of flower.
I've noticed that the tips of my leaves are beginning to go yellow / rusty.
The majority of the plant's leaves are the same, that is, beginning to go yellow or rusty.

I do have a fan blowing on top of the canopy and suspect' this could be a mild wind burn.
I hope it's not related to nutrients.
I grow in coconut core, run to waste.
My return waste PPM on average around 900 to 1100.
What are your thoughts?
Thanks.


A little bit of nutrient burn. Typically it's nothing to worry about - unless you're seeing other problems along with it.
