any idea what problem this plant has?

ok i'm not a noob and i've grown several plants. in the current run there is 1 plant that seems to be acting up. she's fed the same as the rest and there are a lot of "the rest" when i say that. they are all from seed. It is my F1 generation on a new creation... none the less. after we crossed the parents and let seeds develop some of them fell on the ground and got swept up into the soil bin. here and there they sprout all over the garden so my father plants them into small containers for me and i pick them up. so this plant was originally in a small 3" pot growing in dirt. just plain old dirt that's been in the back yard for eons. when it came to me it was small and grew slowly as did the other 2 that were in the group. once they became female they were transplanted into real soil and most recently were transplanted again into the pot where they will be flowering. the other 2 that were in plain old dirt show other deficiencies which are easier to diagnose but this one...i can't figure it out. there are a number of things going on and it's really weird. it's the older leaves so it's a deficiency. the new growth is normal but i'm not about to flower this girl with a problem that i can't figure out. so before i uproot her and dump her into the compost pile...any thoughts?

i don't care about dumping her into the compost pile she's one of quite a few and my patients deserve only the best.

it looks like a nitrogen deficiency

hi, im havin simmalier problem the patchy spots on the leaves is how mine started then fading leaves turning yellow and eventually rusty spots then dead leaves, ive been treating for a mg deficiency but re submitted the question today and have been told to feed as it looks more like a n problem, so just need to feed, my thread is "mg by cozz
hope this helps in some way and good luck

i figured it out as a few other plants had the same problems appear. i got lazy one day and was running short on time to water the girls. so i busted out the garden hose. 800+ PPM's. god only knows what is in that water. my mothers can handle it as they're all much older, but the younger plants really have no idea what to do with the heavy metals that are floating arouding in my tap water.

So cal water is nasty and grey at least in the IE it is.
