<doh> Sorry, I thought you said you were adding molasses and calcium, which sounded fine. Molassest has some calcium, but have never heard it used for corrections.

Are you letting the soil dry out properly between waterings? I've seen spots like that, on plants with overwatering problems. I ran out of perlite a ways back, and had just got a 15 lb box of worm castings, for ammending the soil. (not as the medium itself, lol) Made a muddy mess that was a bitch to keep on a regular feeding/watering schedule. Ended-up with minor root rot but finally figured it out after transplanting to better soil mix.
Just a thought.
Rusty Trichome Reviewed by Rusty Trichome on . Multiple Problems Hello again everyone!! I just put my plants into 12/12, 3 days ago and changed the nuets and I have got about 3 problems already. Mites - I have dealt with and will continue to. Yellow to brown spotting on middle leaves. They also are getting discolored edges. And also leaf edges are curling and some appear ragged or torn.
