Yellow spots on leaves

Hey guys,

I have a few outdoor ladies and I noticed during the last few weeks a few of the bottom leaves were yellowing to a dry crisp.

I think that's normal but over the last few weeks since flowering started the leaves have gotten yellow spots on them that have gotten bigger.

I am guessing its a deficiency of something because I haven't used any nutes. Should I just add some NPK to there diet? Or should I just give them P and K?

Thanks to anyone that can reply with some knowledgeable info.

The bigger they get they lower leaves yellow and die, cut them as you see them turn, VERY IMPORTANT. Cut next to the leaf let the stem die off and fall off by itself.

yeah you should feed them...i don't think you should pick them till they die and almost fall off by themselves...
chrishydro why you say "cut them as you see them turn, VERY IMPORTANT."

why so important?....

Lol I was wondering the same thing ^^^^^
