Leaves look like they have rust on them.

Yesterday I went out to look at My mama's and discovered That appeared to be rust on marijuana leaves.

A couple plants are looking like they're missing something and I don't know what it is. could someone please help me and maybe help me identify what nutrients I'm missing.

Are you feeding them? It could be calcium or magnesium, that's said a common problem. It's starting on the lower leaves so is a mobile-nutrient issue which may rule out calcium. Not sure what kind of growing system I'm seeing with the irrigation pipe and funnel. Wanna tell us more?

I assumed it was a hempy bucket of some sort. It does kind of look like a nutrient issue.
@NORMANREH41 what's your nutrient details? What's with the lower damage near the circled area in the first pic? Leaves look a bit beat up
 
Is that all you're feeding them? Just nitrogen? I give my plants 8 different chemicals per gallon, most folks just buy some brand of nutes cause it's a lot easier!

I'd try Epsom salts, a gram per gallon, if it's magnesium deficiency, that should fix it.
 
Yeah rust would be a cal/mag thing, but not necessarily because it's lacking it in the media. It could be being blocked because of pH issues or nutrient build up or improper ratios. Are your plants yellowish light green like it appears? Or is that just a lighting thing?
Also it's hard for me to see well enough in your pictures to say for certain. When I zoom in I can't tell if I'm looking at a deficiency or pest damage. That's why I asked about the torn/chewed up leaves.
A full run down of your grow would help. I've never seen wood chips used like that before. Maybe there's more to this story?
