Check out the Helpful links in my signature to better ask for help...so many unknown variables that need to be presented for any decent feedback. People will help if you meet them halfway.

It is a lot easier for us to diagnose a problem with pictures of it as it is occurring and where it is occurring on the plant. It also helps to tell us how old the plant is, if it is soil or hydro, indoors or outdoors... the more details the better.

Copper deficiency would be rare... and probably not on these big lower leaves would it show. The few spots I can see here look to be how a magnesium deficiency presents, but again, without knowing where on the plant this is occurring, this is simply a wild guess.

are these autos ?
what is the light schedule ?

couple things :

look mostly ok really
colour seems good

bit of an up curl - could be light / heat / nutes.
for the life of me can't remember what an up curl means in nute deficiency / excess

probable predatory damage in the lower part of the first pic.
most likely mite.

it might be powdery mildew. i can't really tell from the pic.

alright... in those last pics I definitely did not see an signs of copper deficiency... now, without removing any leaves, zoom in on one or two that are showing you the problem... I think I saw some in your picture but I wasn't sure. You water a little unconventionally, but the plants seem to be tolerating you just fine. I see healthy plants... but maybe a slight magnesium problem. I don't see an upcurl or any stress at all indicated by the angle of the leaves. More pictures are needed.
