Deficiency on CANNA line?!

Hey guys straight to question?
What deficiency you think that is? Or toxicity?

So Im indoors grower and Im using canna line
Lung room +20c - +24C humidity 45-60%
Tent room +19C - + 27C, humidity 60-65%
Im in 3 gallon autopots and Im just in day 1 of flower nuts veg 3,6ml/L just bumped to 4,5ml/L and cannazym 2ml/L 1,7ec, ph 6,3 in my reservoir
So I noticed a bit of yellowing going just before I went to flower, but no probs soon as I flipped to flower on day 1 it went like that, brown spots yellowing etc, and the only thing that I changed what I start adding canna cal-mag 0,26ml/L (that is the first time added) and Im in soil.

so Im thinking its potassium deficiency and thinking to add raw potassium to pot, what do you think?
So is it cal-mag or potassium deficiency or my guessing is wrong? Maybe Im feeding to strong but they had 5weeks to mature already, thing is that plants like glookies that are next to them are loving it and pure green.

Any ideas? Help me out!

Thank you in advance

overfeeding led to lockout. or you have root issues. or your pH is off. or all 3

You are burning the hell out of them. When I ran canna I never went over 750ppm and that’s with a dialed in environment and top shelf LED.

Canna cal mag has alot of nitrogen in it no?
I'm in flower and when I feed cal mag I use 2.5-3ml/L of the other nutes, so half of it. (possibly add a little PK13/14 depending on how my plants look)
And cal mag itsself 1 ml/L tops.

Be careful with bombing your plants with nutes my friend.

pH is 6,3 no probs roots seem to be fine maybe a bit drowning in autopot but normally always works

Im sorry my bad its 1,7ec not 1740ppm…

i don't grow in soil but maybe the constant wetness of the soil in the autopot is the problem? isn't soil supposed to have a wet/dry cycle?

I'm just wondering aren't autopots usually for coco? If it's soil he's using that would make sense, since it holds more water and if it holds water constantly... it could be root problems after all. I'm just speculating here guys ... sorry if I'm bothering anyone.

It is thats what Im thinking as my second opinion I had that problem before when plants start drowning and they dont absorb that much oxygen but even tho is pots shows about 40% humidity in pot Im still leaning towards deficiency or toxicity as plant next to them a lot smaller but all fine and green but clones are fucked

It's puzzling to me.
Not the best with identifying nutrient problems.
Looks a little like the iron deficiency here in the picture:


Question remains: what caused it / is it a lockout or is it PH based.
As far as my personal experience goes, I've mostly dealt with toxicities cause I thought "enough wasn't enough".
Humans tend to be happier telling themselves "Ah, fck it bit too much" rather than "Damn, they needed more and I didn't give them enough"
So that's why I'd say you can't really harm them if you skip the nutes for a couple of waterings on those particular plants.

What kind of soil? And do you always have nutes in the reservoir?

I have been growing in SIPs for a bit (same concept as autopots), and try to only feed dry amendments directly in the soil, and only use plain water in the reservoir. In the rare instances I do give liquid nutes, I always top-feed. IMO, nutrients in the soil, plus nutrients in the reservoir, is just asking for trouble.

I can't see what you're using 4-5ml of + canazyme...
If that's a+b your talking about it's way too strong and especially so for a autopot and early flower.

3ml a+b gives 1.5 ec idk how you arrive at 1.7ec with the amount you're using.

Im in biobizz light soil with a little bit of old soil with could be the case of problem Im dry amending it at all on this go this is pure salty canna line vera/cannazym/ryzhotonic for veg terra/canna/ryzotonic/booster for flower and feed is always in reservoir no water breaks

Im using vega/tera cannazym rhyzotonic booster Im in biobizz soil.
So thing is that my feed is
4,6ml/l vega
2,5ml/l cannazym
And this was the first time I added cal-mag from canna line 0,26ml/l so call mag bumped my ec a bit also tap water is got a bit more ec like 0,35-0,45, so Im confused maybe they are drowning a bit as I normally give them 4wks veg this time only 2wks of veg, maybe plant was a bit too small and start drowning, just seen video from Vader OG and I think Ill try to use ryzhotobic 25ml/L for foliar spray them today also gn try flushing them and gn let them dry out a bit what do you think?

Okay yeah I'm gonna go with overfed as well. Soil with nutrients already in it, sitting in water with more nutrients added to it... Not sure how to fix it at this point, but probably couldn't hurt to give plain water in the reservoir for a bit.

You're only on day 1 of flower? And only 2 weeks veg? I would be scared to flower a plant in that kind of shape, I'd sooner take clones and start over tbh...

Autopots with soil seems not great. Aren't they better suited for coco/perlite?

Not according to their website.
But I agree with you though

You are supposed to feed low EC in autopots @420mlet

Because there's no run off

Yea I have seen that, seems not great.

Idk where I'd start, I'd stop using everything for starters, when I used nutrient again it would be sparingly in soil.

Autopots are a sip at the end of the day, if you put a healthy plant in and keep it fed it'll grow fine, that said I agree with others it wouldn't be my 1st choice, coco or perlite, personally preferring perlite for autopots.
