Hi, i haven't got any pics up yet of it, so will try my best at explaining.

Basically they are still growing, maybe up to around 4 foot tall.
The leaves up near the top of the plant sort of look a bit shriveled around the edges and are a deep green color.
The larger leave at the bottom of the plant and maybe a 1/4 of the way up have some brown spots on them and are a lighter green color.

Does anyone know what may be causing this and what to apply to possible help them out?
Was thinking maybe Epson salts, or aqua soil
but was thinking the brown spots might be too heavy on fertilizer, as i am feeding my pumpkins and the left over is going to the sunflowers
Any ideas would be greatly appreciated.
Cheers.

Thanks for the link, unfortunately not what i have, but good information.
Soil ph is sitting around 6.3 -6.5
It is mainly the leaves up near the top of the plant that are a bit curled around the edges.
Thinking it might be too much K, maybe an application of epson salt to put a bit more N in the plant might help.

How close together are they planted?... Does the soil dry out im between watering/feeding?..

I have some a meter apart and some a meter and a half apart.
It is a clay based soil but pretty loose, you could be spot on as in not enough water.
Are they a heavy drinking plant? first time really growing them out by themself, usually in vegie patch

i would say they like moderate moisture while growing...Maybe give them a good watering and a balanced fert for now.. like miracle grow.. Water down the whole plant...also... Keep weeds away from stalk...

Cheers, will see how it goes with a bit more water on a few plants and a little balanced fertilizer on some others.
Appreciated.
