My friend has a problem with his plants , I should have more pics and information tomorrow, but at first glance would anyone know what it might be ?

Looks like light burn, but it's odd, because it seems like only one leaf is affected. Is there something different about that spot in your grow? Like a fan blowing that direction or something?

Its hard to know without knowing how that plant has lived because many problems have similar effects. Maybe this link will help you and Im sure more people will chime in with questions for you to understand how those plant lived and hopefully get to know why.

It can be hard to identify the cause because a lot of different things can cause similar symptoms. Today I’ll break down all the reasons you might see...

In my case, when that happened to me was nute burn. But it could also be a potassium deficiency, or other things.

Other tips are showing symptoms, so I think it’s light burn too

What light are you using? What potency if its regulable? At what distance from the plants are they? Does it seem to affect only or mostly the upper leaves? People so far seem to agree that it might be light burn, so I guess those are the most relevant questions to ask.

could be light burn, but it looks like a classic potassium "K" deficiency or lockout.
