Some Pale Leaves and others with a rusty color?

[razzapiggy]

Not sure what this is... the pale leaves looks like N diff. but I am not sure what the rusting is. Usually when I see this rusting it's on the bottom 1\3 of the plant, but I have some plants with it up near the top.

Any clue? Can try to get some pictures up but I can't find the USB cord for the camera as of right now.

bump.

also thinking about sulphor bomb for a bit of mildew. i am four weeks from finish..is it too late?

Rusty is often a K def, and Pale is often an N def or heat stress.
That's early to be showing the pre-harvest N def; it should not appear significantly until about the last 2 weeks before chop.
Go ahead and do a foliar feed with a weak solution of your bloom nute, with maybe just a bit of grow fert mixed in too to give a SMALL nitrogen boost.
Check the pH of your runoff out of the pots to eliminate pH problems (lockouts) as a cause for the problems.
Find that usb cable! Pics are pretty important in a case like this.

you'd be better off starting your own post. this thread is over 2 years old!

go here: Plant Problemss (http://boards.cannabis.com/plant-problems/) and hit the big "new thread" button on the upper left part of the screen, just about the thread list.

you'd be more apt to get responses this way. also, fill out the troubleshooting form in my signature.

good growing!
