Jilly Bean SOG strange deficiency in flowering week 3...halp!

I could really use some input here. For the record I've got 23 Jilly Beans on an E&F 4x4 lit by a 1000w Adjust-a-Wing. I use Hydro Fuel Bloei with Liquid W-8, Massive, and Floralicious.

And here's my story. About three days ago I noticed a single leaf had turned "rust" colored near the tip and dried up. I'm not one to freak out about a single angry leaf so I pulled the light up a notch or two, leveled off the Ph and called it OK. Yesterday I go in and three more plants have joined in and another three are showing the earlier signs of whatever this is. In it's earlier phase the leaf seems to lose some of it's 'green' and 'shine' and that same area slowly turns rust colored while it curls up angrily. I've also just noticed the petioles of the affected leaves have turned purple, showing red near the very base of the leaf.

After some panicking and searching online I decided the problem could be a phosphorus def, as it appears in the "marijuana plant and pest problem solver" that's floating around on so many forums to look alot like what I've got going on. It makes a bit of sense as the solution had only the "Massive" bloom booster and lacked the usual phosphorus loading bloom booster. So I added a healthy dose of KoolBloom and did a foliar spray as well.

Here's where I'm confused though. In my last crop of Grand Daddy Purple I had a more typical phosphorus def in which the lower leaves turned an almost black purple and curled downwards. Ph analness and koolbloom solved that, but this looks 100% different.

I'm lost, if anybody has suggestions I'd love it. I have no clue what's going on here.

I could be wrong but it looks like what I just went through N overdose have you flushed? Thats first priority it usually helps but yours are a lot more curly than mine.. It looks similar and I just had to chop the whole mid section of fan leaves they all turned black(had nice lush purp leaves) but now they're all gone haha, flush and flush again if it doesnt come back cut it they will attract bugs/mold.

there's no sign of overfert anywhere nor is there any excess green, they're practically pale compared to my GDP table next to them. Also, if anything, they're a bit N def and showing it with a few scattered chlorotic lower leaves.

nothing else? no other good advice?

might be an iron problem or Phosphorus

Fuck that noise, its Magnesium..point and match

Wanna know how I know, cuz im gonna ask if your using cal/mag and your gonna say no......right?

Looks like Mg deficiency to me.

...mmmhmmm

Looks like a mag. deficiency. Epsom salt! Or Calmag of course...

Razortips on sides of leaves are burned, yellow between leaf veins and clawing leaves. Tell tale signs!

Actually I use LOADS of it. Raving shitloads. I was plagued by Cal Mag problems to begin with. Now even the water I top off with is brought to 250ppms with CaliMagic before I do anything. 250ppms is insane high, most people I've talked to go to 100, maybe 150.

Jilly Bean likes to show yellowed edges with a mag def, but the edges don't fry and get crispy. These edges are super crispy.

As an update, it's gotten much worse, look at the fan leaves I just had to cut off. Some seem to turn rusty red, some this sort of death grey. Either way they're curling up and it's the top bit of the plant that's effected so if it's a nutrient it's mobile.

That pic reminds me of a Sulphur def.
