I also have a question for @MrSauga and anyone else that recognizes or has an idea what this looks like. The chem og auto we were discussing the other day. Went in this morning, pretty much exactly 24hrs after watering it back at a straight 3.6gs of MC feed, that it was taking just fine before its one feed with lower mc and supplements.

Does this look like lack of N? I ask that because that is what I was warned might happen by the sauga himself

Its different than anything I've seen yet, or at least recognize any kind of readily.

Its like the leaves are nute burning, except not, the end retain more green color than I've seen in other cases. And the spread pattern of it on the leaves is different too. I thought low N would just cause yellowing?
 
Lol what’s up shed, how you been?
I've been okay! All well in the great state of Ohio?

N def is yellowing of the lower leaves. That looks more like a P or K toxicity.
He must be making the move already ,we know he sold his paradise in the mountains.
Damn, I am so far behind on his journals...
 
Oops @InTheShed hope they don't mind me tagging them here that way. I am gonna go find their threads and show some love there too. Just trying to get their attention in a friendly way I guess.

Hey @Pennywise thanks for swinging by!

If you were in hydro I’d say look at the roots but that’s out .
Grandpa Tokin bought a place in Florida, don’t know where in Florida!
 
Dropping the MC to 2.8g/gal seems risky imo for getting deficiencies. I suspect your plant will start yellowing at one point rather quickly from the lack of N. By dropping the MC you've reduced the other nutrients available to the plant as well, such as N, Ca, Mg, silica and more. Look at the images below at the ppm levels your plant is receiving at 2.8g(not including what you are giving with the BE and SC) and what they could be getting if you were at 4.5g/gal without the BE and SC. Having said all that, being this late into flower and you may not notice anything at all.

Oh, and @MrSauga , I fed the flowering chem og back at its higher MC dose of 3.6 w/o supplements this morning. She was showing no signs of stress from the previous feed, but I am going to follow your advice and get the straight MC dose up to at least 3.8, probably 4, then carefully add some SC and start her on the gravitron! She is an auto after all, and I'm scared to go all the way up to 5 grams/gal MC for fear of roasting her! We're probably 3-4 weeks at most from finish. Next Wednesday is 50 days in flower for her, and the breeder claims 55-60.

That happened fast after one feeding. I can only assume it's from the extra feed. I'm a little confused why 3.6g is doing that. Naturally you'll have to go back to where you were at Moe and see if the damage stops. That was less than a gram increase and well below any dose that I have seen cause an issue.

Did you adjust your lights recently? Any damage on the lower leaves?
 
Ohio huh? @Pennywise . I had to swing into Ohio yesterday for work. Bright lights big city of Aberdeen. I'm in good ol' KY! Sure wish they'd get their heads out of their asses here!!!!!!!

As for the chem og auto, things are no worse this morning...so it looks like she didn't like the bud explosion or sweet candy. Ill just bump the mc dose a bit and see how she takes it.

3.6 is where she was before I decided to get squirrely and drop the mc and add in the supplements, no change in lighting (just the usual rotation of the plant every day or two), and no damage down low to speak of.
 
OK I'm confused. A post earlier said you didn't add any supps...

and now this...

Drop the supps and you should probably reset your substrate now as well. You may find running some fresh water through her instead of a full rinse will be enough and feed at the end.
 
Before I ever decided to try her on the supplements at all I had her feeding at 3.6gs straight mc.

Then I decided to do the whole drop to 2.8 and add in SC and BE to see how she took it. This is when you reminded me about the mc calculator and pointed out that I was taking my N levels to an iffy place. So it was too late at that point, the modified, supplement enhanced feed had already been given.

So here we are today, two mornings ago I fed her back at the 3.6gs of straight mc with the intentions of getting that number on up to 4ish on the NEXT feed (which will be tomorrow when I get back into town)

So last three waterings were as follows
-3.6g mc
-2.8g mc / .25g be / .25g sc
-3.6g mc

I went back to 3.6 after the one modified feed once I saw the info you pointed out to me. She only got one feeding that was different.
Thanks Moe. It's starting to make a little more sense now. Can you post a pic of the BE and SC analysis labels? You're not seeing any of the lower leaves start to fade are you? Are they maintaining their greenness?
