Just need a second opinion

Hey everyone, just want a quick second opinion here as I'm thinking mag deficiency, but I have never seen it quite look like this. Any help would be greatly appreciated.
Autoflower cannabis
Ph going in- 6.2--6.5
Ph @ runoff - 6.5 (fairly consistently)
Mega crop ~3g/gal
Sweet candy ~ 1g/gal
Blue planet nutrients cal/mag - 3ml/gal
Coco loco/perlite mix. I add another 1\3 of perlite to the coco loco mix. Has worked great for many many runs.
Running 3 different mephisto strains, this is heaviest on two.... Fun fact- don't get peat pellets mixed up, you WILL lose which strains are where..... Haha. So yeah. But these symptoms are seemingly spreading throughout. Under sides of leaves are fine, highly highly highly doubt pests. But don't get me wrong, I know I'm the one asking the question here, so im all ears. My main concern here is that I have never seen symptoms quite like this before. The dead patches are obviously in the margins, but interesting patterns. Top section is seeing these symptoms, while mid fans are experiencing chlorosis throughout and necrosis spotting in margins. Thanks, I can add whatever to this list, just took a couple dabs, so im getting lost in this now Hahahaha. Thank you to all, im interested in hearing what you guys got for me.

Im guessing mag...... But again, the pattern is different for me. I, luckily, rarely run into deficiencies, but my mag experience is a bit more "blotchy" I guess.


My first guess would be Magnesium, And possible calcium if its found on older growth.

Theres a thought i'll call it that running LEDS are causing plants to uptake cal-mag in rates much higher then previous HIDS .. Its never been confirmed 100% but I've seen this 100 times with leds.. Don't see it that much with HPS/MH/CMH ect tho.

I have also found that to be regardless of what I hear as well. That is also my thoughts here. Just pattern is crazy. I will attest that this is only like my 6-7 auto run and definitely my largest at 12+ plants. Momma needs a vacation so that means dad's gotta step it up from time to time. Hahaha. Thanks a ton for your input. I'm glad I'm thinking at least similar to some other's. Also, def check those leds my friend. You'll be impressed, not because he's my buddy, but they are stand out as hell. Once you hold and see one vs basically a lot of others out there, you'll be like "ok, i get it". Take care my friend, appreciate it as always!!

Foliar spray with epsom salts for a week and watch new growth, Add epsom salts or increase cal-mag and watch new growth if you don't see it getting worse or new growth showing the same problem then ya got it under control :D
OK, cool, another friend in agreement. You say a week huh? Excellent as that my other question. I'm assuming this stems from me stepping down out my comfort zone and into 2 gals. That's a small pot for me and I think that in combo with the unintend/intended sea of green I have going on, it has shown me some things I'm not used to. I have begun that approach already so I will go another week with it. Should, in your opinion, continue the up in cal mag at the roots? Or one or the other approach? Thanks very much appreciated.

Apologize, I was bouncing back and forth between posts. But thank you for the info on the cal, obviously the led thing doesn't necessarily apply to you. Hahahaha. Man, that cookie kush does a number!!!

I would also add extra to the roots yeah, I've been dealing with it my self caught super early but alas damage was already done. I supplement Cal-mag around 2tsp per gallon, Then i also add extra epsom salts to the soil to prevent any lack of in the future.

Right on. Yeah, im a bit out of the comfort zone here. So I appreciate the advice. I'll give it until next weekend and report back for the next guy. Can't believe how fast this came on. Literally in two days, from fine to that. Caught me off guard for sure. But I know I pumping the leds on em so in hind sight it makes sense this would pop up right now. Thanks again my friend.

Its a pretty quick moving deficiency almost hard to spot at times till its too late, Heavy N feeding at times can hide it till the whole plant starts to turn lime green and then its like oops! LOL

First time i seen it on mine i was like oo this is cute whats going on, next cpl days im like oooff shit this is wrong so wrong!! lol

Hey, im not too proud to ask, I do not foliar feed. Just haven't really. I'm going distilled water, no ro here, and a half teaspoon per liter. That's a spray bottle I have, 1 liter. Oh, half teaspoon of Epsom. Ph it 6.5? Thanks.

I generally never did either, But i figured it was the fastest way to cure the plants illness and ever since i started doing that its worked out well for me so i pass the tip on :D

and tbh i don't really measure anymore I just grab the salt an toss it in the spray bottle and shake it up.. If it looks like 1-2 tsp then ok :D

I've yet to burn my plants with cal-mag, I reserve most of my burning for nitrogen fertilizers lol ;)

Keep me posted I feel invested in the health of your ladies now lol

and yeah just PH to whatever you normally do. .if 6.5 then yes :D

As you should damn it!!! Hahaha, nah, much appreciated. Honestly, I don't typically post "what's wrong with my plants!!!!!" posts. A. I read and study and grow a lot. B. I read and study and grow a lot. Hahah, but seriously, this one and the quickness. It's actually still progressing and pretty bad. Leaf tips are turning into the wicked witches shoes man. Got some work to do, something isn't going as planned..... Will update you, np. Thanks again man.

Hey brotha, just wanted to report back on this situation, one, to thank you for your help, most definitely, and two, for the next guy in a few years. As we thought, mag deficiency, with a dash of cal deficiency. As per usual, after my posts it did continue to get a bit worse for about a day as it mellowed out from my addition of cal mag, epom salts. I added both, blue planet cam mag. I have to say I am not really a fan of it. I am going to try tps oac cal mag starting today and hopefully like it much better. Anyway, I also was spraying down the plants with Epsom salt ph bal water. I personally went with a half t per 32oz.as that was my spray bottle size. Ph was 6.3. I did not take a ppm reading on it, sorry if that's what you're after. I have used this spray before and as it was said before, as long as you don't get silly, a half t to a whole t should be fine. Sprayed at lights on every morning, dimmed my lights for about an hour as it evaps. And noticed the first sign of improvement about 2-3 days into the process. As of this morning, things are very close to normal, growth is getting back and flowers are back at it. Thanks for any and all that helped. Little dabs, much appreciated for your time good sir/mam.? Another lazy mistake avoided. I realized this whole thing stems from not adding cal for a handful of waterings in coco loco, under high output leds. I know I know, it's been a hell of a last couple weeks here. Anyway, thanks again, smoke report on the way!!!! Haha.

I am glad you got the cal-mag issues solved. I am going to post that folier spray formula on my bulletin board in case i run into this issue again. I was just looking at your POTM picture. What in the heck is that growth i am seeing that looks like teeth? Never seen that before.
