OK, to prune yellow lower leaves or not?

[goddog]

i looked through the trouble shooter as suggested and found that my curling under leaves may be a n overdose, so ill col it on the ratio.

but.... on my 1' plants i am getting yellow large fan leaves, like 1-2 on each...

do i cut them? i dont think there is any chlorophil in them at all.

are you in flower??
If so its normal for leaves to go yellow.
Or you have a Nitrogen diffecence.
Leaves curling under could also be too much water
