I'm in serious trouble. As soon as my plants came up from the dirt they've started dying. The lower fan leaves develop brown spots, then turn yellow and finally wither and die. And so it goes.

I'm growing AK47 in 2 parts ordinary flower soil 1 part perlite and 1 part vermiculite. They're under a mixture of warm white and cool white fluoros and the temperature is a steady 22 degrees celsius. I can't figure it out. The soil is new and should have enough nutrients. The water is the same as I've always used. I've had amazing success before in this "closet setup" with other strains, such as Jack Flash, Hindu Kush and Shiva Shanti. I once had a magnesium deficiency with Jack flashes and this problem seemed similar (except it didn't show up immediately) so I've added 1 tablespoon of Epsom salt to 2 liters of water last week, but to no avail. I've also tried different water (bottled mineral water) and I've tried spraying them with a very light solution of nutrients. Same thing. No result. A few questions:

What's the best way to proceed? Should I continue with the epsom salt? Is this batch saveable? Should I scrap it and start over? (I really don't want to until I've figured out the problem.) Did I start the Mg treatment too late? Do I lack N? The water I use have a pretty high iron content, could that lock out anything else, like the Mg or something?

Any and all feedback from you experts out there will be much appreciated.

Sincerely, Troubleman
