N is the indicator with MC. Too green or burnt tips means too much.

In all honesty guys, I have not used MC or any other nute, I grow in LOS. Having said that, one thing I have learned over the years that “the simplist solution is usually the right solution”
If those dying leaves are more than 12” below a thick canopy, the girl is likely just shedding excess baggage. LEDs, and it doesn’t matter if they are COB, QB or some other format, only have about 12” of penetrating power. Foliage below this point doesn’t receive enough light to thrive and as such, our girls will pull resources out of that foliage and then shed the leaves rather than put energy into them. It’s a survival mechanism to minimize being shaded by taller plants and allows the energy into building tops and upward growth.
As you are using MC, this may not be the problem, but in LOS that would be my first guess.
Just some thoughts from an old man who lives by the KISS principle
What rate did you settle on with the BE and SC?Mine too... seemed to love MC at 4.5-4.75 and given at that rate I was also able to use BE and SC. The additional supplements would have been locked out, useless and probably harmful if I had been using 5g or above of MC.
If I decide to ever use MC again (BIG "IF") I will only grow 1 strain. Too hard to deal with when you have to mix 3 - 4 different strengths. I grew 9 different strains with AN all the same dosage all the way through & No Issues like this stuff is giving me.
Yellowing is all on the bottom leaves. Plants are about 2' tall . Here's pics from top.
all my strains are grown on the one mc mix. i do not tailor. i do choose a "problem child" and shoot to keep that one happy. if the hard one is happy they all are. actually found it miles simpler / easier than mc
AN refugee. will never go back. especially after learning about their long term market plan.
there are other nute lines out there. been hearing about a few more dry nutes like mc or jacks (?) - some two-parts etc.
mc isn't the only thing in the boat.
The pots are 5 gallon. Did 5 weeks of Veg & I'm on week 5 of Flower (1st day of Week 5)how large is that pot ? leaves are getting eaten from the bottom.
plant looks like it might be big enough for up pot. or should have been flipped. could be a contributing issue.
6.5 is way hot for veg. it's near max for most flower runs. i recently ran 7.0 at max in flower and it was a nail biter. we pulled back right after plateau.
running without ph in mc is a myth perpetuated by a group of kool aid drinkers in the mistaken belief it is jesus juice.
ph still counts - especially if other parameters are at the outside. greenleaf never told anyone to not ph. ever.
There are a lot of “experts” out there.The pots are 5 gallon. Did 5 weeks of Veg & I'm on week 5 of Flower (1st day of Week 5)
Switched to 12/12 5 weeks ago.
Only got to 4.5 gr. in Veg. Increased .5 grams at a time during the past 5 weeks.
I'm believing the pH thing is a Myth at this point. I'm almost positive this is all being caused by pH issues. After Flushing 1 plant Run Off was 5.6. After Flush on another Run off was 6.4. And after Flush on the last one Run Off was 7.5. Shit was all over the place. All 15 gallons of water for each plant was pH'd to 6.4 going in but came back with all different Run Off Ph's.
Never had this happen with Regular Liquid Nutes. If I flushed with 6.4 I always got run off between 6.2 - 6.5. Not with MC.
Everyone tells me not to worry about Run Off pH & only about what you put in. And then contradict their selves by saying No Need to pH MC. Makes no sense to me.
This is sounding more & more like a pH issue to me.I'm in hydro 5gal buckets, first grow using m.c i'm at about 4 weeks in still using 2 grams per gal for about 3.5 gal of ro water, i ph mine to 5.8/5.9 because i tested a few times in the a.m to find it at 6.4 to 6.5 so now i do test every morning and adjust from there. Also my silver haze seems to want cal/mag to keep her happy at change i add 5ml, and yet my old dirty biker doesn't take any, guess it all trail and error. Good luck.
I was told that doesn't apply to Ver. 3 MC. That they adjusted the formula so it's not needed.Straight from the horses mouth.
I will say that if I’m only using MC, after mixing, I am at 6.3-6.5 every time. It drops to 5.8 when I add in SC or BE though.I was told that doesn't apply to Ver. 3 MC. That they adjusted the formula so it's not needed.
Hmmmm.

That’s exactly why I emailed them. Getting conflicting answers from everyone.who told you ? greenleaf ? if not no follow ...
No, Not the Plant. A few people who are guiding me through this 1st grow using MC. It's all in my journal.Told to?! By the plant? Noo. Those leaves are screwed you're just grasping at straws man.. A true calcium deficiency will be near the top.
