Marijuana leaves turning brown

A question from a fellow grower:

I’m having a problem with leaves turning brown. I removed fertilized water and replaced with pure Distilled water per info in guide, and still or worse browning. Please help.

Brown leaves might not be just from over fertilizing, it can be from over watering as well.

There may be a lot of damage at the root zone and more drastic measures might be needed, like foliar feeding.

Check out these links on ILGM about nutrients, deficiencies and foliar feeding:

And feel free to come back if you have any more questions.

Pictures of this plant would help us identify the issue a lot faster, with an informed recommendation. :slight_smile:
