Light Box Grow

The tips of the leaves are turning up and browning.
It's not the led lights. Running cool.
I spray twice weekly with usual nutrants and dredge similarly.
What else can it be?

That's called "Turn And Burn". Means your girls are getting fed good. Just back off your nutes a little and you will be fine. I always look for a little Turn And Burn. Means my girls are going to be happy.

Yep. Just back off your nutes a little. And I'm sure you already know the damage at the end of the leaves do not repair themselves but you will see the difference on the new leaves.
