Ok so this is my 3 rd grow and every time I've had the same problem! I managed to get thru the last two barely !! No where near the yield I should get. So I built an indoor cabinet with fans cfl lights and led panels surround by Mylar! I use sensi grow/bloom and use hobbiest bundle including big bud, b52, voodoo, and over drive! During my veg cycle I use nutes/water/..... Using sensi grow a and b and b52 and voodoo on exact schedule that advance nutes sets up. I'm pretty sure it's not nute burn because I'm a lil experience with vegetables and have these plants at first with no more than 700 ppm while having 3-4 sets of leaves now at 1000-1100ppm using distilled water. And obviously lower at beginning to get them used to the nutes. They are in aerogarden ultra base with plenty of air stones and have big white roots and I use my own higher powered lights on 24 for veg !
everytime at first a lil upwards curling of leaves as they get there first nice fans then after they get bigger maybe weeks 2-4 of veg cycle they come done with what I have read as chlorisis where only between the veins do I see yellow spots that eventually turn rusty! As I moved them up into my "bloom chamber" changing lights, nutes, and giving a 12 and 12 light cycle they just seem to get worse at the same pace as in veg. So by the time it's flowering the plant starts to look like its struggle and I barely get threw the cycle. The only really similar deficiency is manganese! My sensi grow/bloom nutes say nothing about Mn and neither my hobbiest nutes. So I was sure it was it but then reading on advanced nutrients website about sensigrow/bloom on website it friggen says that it balances the Mn and Iron perfectly so they do not mess or counter act one another God dammit please helpimage.jpgimage.jpg
 
I've found when I get upward turning leaves I need to give my plants Epsom salt, one tablespoon per gallon won't hurt.

ive got a similiar looking issue, but my rust spots all started in the center of leaf like phos def. but they spots look more like mag defDSCN4222.jpg. ill let you know when i found out what it is just in case. At the very least. a free bump XD
 
nutrient burn flush for one week, nutrients should not be used untill at least week 3, only root stimulator for first 2/3 weeks. To much to soon!
 
While the leaves are darker than they should be which means overfeeding, this isn't nutrient burn. It's a deficiency.

Looks like it needs some cal/mag. What does the new growth look like.
 
one question, have you ever flushed? your lights and system are small compared to a HID room with perfect temps and 1500ppm co2 so your not going to be able to crank up the nutes like normal feeding schedules say. if you have been flushing every week to 10 days then I would suspect a possible ph problem or water temp being to cold, Ive seen similar problems arise out of nowhere only to find out it was a ph problem steming from a ph pen that was giving false readings. I knew everything was right on but also knew it had to be some kind of ph problem, a new ph meter and man I felt like a dummy lol. hope this was some what knowledgable
