Hey guys, how about a hand with this?!? Pics

These are some Purple kush clones that have been in my modified Stinkbud Aero system for almost 2 weeks. Feeding Botanicare nutes and had some initial probs with ph the first few days but it's straight now.

Check out the pics below. I have never had rust before so I can't tell if this is it. Looks like something else to me. It's kinda rust colored but very reddish. Seems to be affecting the middle of the plants. Any takers? I could use a hand here. Thanks in advance..

Yea def a cal/mag def. I would lean more towards Magnesium. Get your ph adjusted and bump your ppm up and add some cal/mag. Should cure the problem.

Comparing your plants to some of these it looks closest to the Mg deficiency imo...

Wow a defiency can cause this? Im running about 850-900 ppm right now. so you think just adding some calmag and keeping my ph right will do the trick? Thanks for the input,mucho appreciated.
