My only worry is that I will then overload the SC plants with N since they are still green but I’m going to go for it at 6.5 and see what happens!
I also raised the lights 2” to give the tops a bit of a break, it’ll also help widen the spread to the outer buds. Thanks guys!

Well it could. If the Mg def is from a lack of Mg then you'll be fine. But if the Mg def is from a lockout then the extra N will create more demand for Mg compounding the issue.
If we stick to thinking it's a hungry plant then the excess N will not affect the potassium or the Mg. Since the plant is in flower the demand for K is increased now and your plant doesn't show any K def that I can see.
The organic part I honestly couldn't care less about, but there being no nitrogen is what really attracted me to give it a try. I've been running about 1ml/gal for each week from sprout, topping out at 6ml/gal after 6 weeks. From there I've been watching, and the most I've ended up with was 8ml/gal. Considering I'm using RO water, LED's, and running hydro, I think that should keep me in the ballpark.

What about just adding 5ml per gal of Calmag then? It will add the magnesium without the N?

I have a line of GH and Reno nutes but I really want to see this through with the Megacrop, it is just so convenient, but I am really not liking the separation issue I’m now seeing with it plus my last grow with GH, although a little more time consuming with 4 bottles went amazingly without these issues. But alas as I said I will see this through with the MC
The only time I like to add calmag is if the plants are at 6 or 6.5g/gal. If that was the case I would tell the grower to dial back the MC to 5.5 grams and add calmag. Your plants will miss out on the benefits of MC if you just add the calmag and continue to stay at 5 or 5.5g/gal. Eventually the plant will be looking for more K so it's good to get up to 6g. If you decide to give her the 6.5g then after a feed or two you can dial back to 6g.

Sounds good sensei, let’s give it a go
You must be a jinx or something. 
One plant (ironically Durban Poison, although the auto version of the one I ran last winter) only. At least it isn’t rust. Already at 6ml/gal of calmag, guess I’ll be bumping that and MC (5.5g currently) up a couple notches. :rolleyes;

Hey all so I increased to 6g last two feedings and then to 6.5 this feed. Unfortunately it doesn’t seem to have done much for the two problem children I don’t think except give tip burn on the better looking plants now. Still having issues with the MC settling as well although I mix it pretty good before feeding, I wonder if that has something to do with it.... One plants upper leaves are absolutely decimated and the sugar leaves are taking a hit now too. The other Wonder Woman that is secondly affected is faring a little better and it may have stopped it in her. The rest of the girls are showing some preliminary signs of the same issue now though...
Frankly I’m frustrated and completely unsure of how to proceed. Hopefully the next few days the 6.5g slows it down, elsewise I may just switch back to GH to finish this run...
Anyone know exactly which nutrient is the issue? P, K Ca or Mg? Here’s a few pics showing how it progresses, upper leaves only.
Starts with a lighter yellow setting in and rusty spotting.
Moves to brown and crispy tips that work inward on the leaves and increased yellowing
A few shots of the two most affected plants
The good news? Well the buds are massive, like bulky as hell! This Wonder Woman strain has some real size, it’s a shame I won’t see what it’s full potential would’ve been. I will definitely have to grow it again. Hopefully though the buds get most of what they need by taking it from the leaves and aren’t too malnourished. Also, the other 5/7 are still doing pretty well and aside from the recent tip burn looked a pristine green. I’m going to remove these two bad ones from the auto system and hand feed them separately so I can return to 5.5g of MC on the rest.
Here’s a few tent shots, still a ton of big frosty buds!
Also on the bright side I framed in My growroom and reran my electrical. I put in a 20amp circuit with 8 outlets and another 15amp circuit with 4 outlets, so I took the power bars and electrical cord away! I also plumbed in a laundry sink for easy res fills and drains and cleanup! Just have to drywall now and set my 3x3 tent backup which now has enough room to go right beside the 5x5 in the same room.
I finally pulled the trigger on a 6” infinity fan and carbon filter, got it hooked up and run through the window in the room,my grow is now fully contained and locked in my new basement room! I’ll get some pics of the work when it’s all done.

Apart from the few discoloured leaves your room looks amazing

Hey McRib thanks man!
It's hit me again too. I think it's calmag, with maybe a tick of light stress thrown in in a few places.
I did some pretty deep digging last night, trying to get my head around it and find ways to get and stay ahead of it. It just kind of amazes me as I've been supplementing Ca from the start, plus MC has Ca in the formula already.
What I've found is Ca builds up hard from the very start. By the time you get to mid flower, give or take, and symptoms like this start to show, it's pretty much damage control at that point and keeping other growth from being affected as bad.
I'm going to also try doing a flush for a couple hours with some flora kleen to see about getting rid of any potential excess salt in the medium. Then I'll drain that off and put a fresh mix in, run it through for a half hour or so to get the buckets rinsed through well, then put it back on the timer.
What I'll be doing from now on is going to be doubling the amount of calmag I've been using from the start. I'll start at 4ml/gal for the first 2 weeks, then 6ml/gal for the next 2 weeks, then 8ml/gal from there. I may even go 4-8-12 instead of 4-6-8. Have to get it nailed down pretty soon, but I'm going to be bumping the little 2 week old up on Ca first thing tomorrow, as well as these other girls too.

I’m suspecting that as well, that the calcium is not dissolving properly and it is what settles on the bottom of my res.
It could be. I don’t have any sediment in my res though. Today is water change day, so we’ll see how it goes (when I can peel my ass off the deck and get motivated, lol.)

Every time I mix I see sediment the next day or a few hours later, I’m not even convinced it dissolves at all even when mixing. It might just swirl around. Maybe I got a shitty batch of MC? I ordered from a hydro shop that obviously bought a larger amount and decanted it.
That isn't out of the realm of possibility.
Do you have anything mixing your res in the interim? Air stone, small circulation pump, etc?

Two large air stones
I think tonight’s feed I will flush with a gallon of water then 5g MC with 5ml per gal Calmag

Calmag first, but I assume you got the handle on that.

Flowering Week 9
Hey everyone! Sorry I dropped off so much the last few weeks they have been so busy, three kids, pregnant wife, pandemic, trying to finish a ton of projects around the house! Anyways here's an update, hope some of you are still here!
Mixed results on this grow. I definitely bit off more than I could chew with 7 plants during everything I listed above, and all of the upgrades to my setup and grow room along the way, but at least I have learned lots and am in great shape going forward. I have two plants that while bulky as hell I could not get their deficiencies solved. One is really toasted the other I may have salvaged and hopefully stopped for the final week or two. I switched last week back to my leftover GH nutes and honestly they just dissolve so much better in my res and with a 60ml syringe it really isn't that much more work to mix 4 bottles. I think I'll be starting with my megacrop next run then transitioning to my Remo nutes when I got the auto water. I'm also wondering if the low flow on the plates was a cause of issues with the flowers. The edges never really would get watered. I'll have to play with it before next run!
Here's a few shots of the girls, either way the tent is wall to wall colas and frost!
Here is a great example of what back building can do. Can you tell which one was snipped and is bulkier?
I bought a new wifi scope that is much easier to use than my loupe, here are some trichome shots! Hopefully looking to harvest a couple more mature plants in a week, the rest the week after. Lots of heads clouding up with the odd amber beginning to set it.
