when do the leaves actually become useless. A few of my leaves have died due to overnuting and have a few messed up ones as well. What i'm asking is at what point do they stop absorbing light and whatever else they do, I have some that are pretty much yellow with brittle brown bits, are they still doing anything at this point?

I heard from my friend that when his leaves died he cut or ripped them off because they wast the THC but I don't know if thats true, sounds legit
he did this when the plant was flowering I think

Hi COOK..

when a leaf becomes NECROTIC.. it will NEVER turn green again..

NECROTIC.. means DEAD lol

If the leaf looses its GREENESS.. and turns yellow or brown, it is DONE...

Usually these leaves come off very easily with a gentle tug..

The reasons you don't want to leave these leaves around -
1. obstruct air flow
2. encourage slime, fungus, mildew

A leaf can turn LIGHT green... because of under feeding.. and then turn a healthy dark green....

it is only the yellow and brown leaves that NEVER turn green again
