Looks like Magnesium deficiency....but ?!

Hi, I have been growing clones in 50/50 coco/perlite mixture..they are now on day 18 .
The clones have been growing fast but from day 1 I'we been adding for precaution
extra magnesium and extra calcium...the main nutes are Canna A+B..I also have Silicon+
in the mixture.
First adding the A+B to the desired EC value, and after adding magnesium and calcium
I have had to add serious amount of plain water because the mag and calcium increase
the EC super high...that of course causes the NPK ratio go down in general in my nute mix.
The plants have been showing signs of patchy coloring in leaves and only at lower leaves is the
color more even. The midlle big leaves look like stone washed (like some pics online showing magnesium
deficiency)...I newer added the max amounts of the extra cal or mag....I did do some foliar feeding
with the magnesium also...the top leaves are twisting and canoeing...the midlle leaves are a bit clawing
My EC is now 1.3 ...to start rinsing and feeding just plain water would be difficult ,I would need to turn of the pumps and start taking plant by plant to the side and have draining container and fresh water container to start
rinshing plants + the growing media dryes very fast..so I couldn't do that for like 5 days ..I am not present that continuously ..and there is no guarantee that it would be the answer anyway..since the symptoms
look like a lack not of a over dose....
Anyway anybody has some true understanding of matter like these...

And sorry I am not going post pics..for the obious reasons..

No pics?!

No pics sorry....if I would live in California pics wouldn't be a problem..

Pffft lol!

A lot of cats that post pictures live in illegal states. No one busted because of RIU, as far as I know.

But without pictures, no one can give you the answer you seek. I mean, "Does this look infected?" Hard to tell without a picture, right?

Yep... true but its still stupidity to post pics without knowing how to clean source code from them...
So I was hoping if somebody could point me to some direction with the clues given...
I'we checked all pics and diagnoses online..and the winner still looks like magnesium def.
If somebody can give some pointers how to rule out that reason By me looking at the plants...

Example speculative answer : Many people will misinterpret these sympotms By looking at the flacky clorosis on the leaves..
but if you look closely so in magnesium deficiency the top leaves are not curling in on them selves like in
zinc defiency...but then again in zinc deficiency the stems are not purple...

And don't even think about suggest Mosaic virus...that is not even aloud to be discussed..

Hv.

Paranoia.

Hard enough to do with pics, without impossible. But I will give you one possibility that isn't a good one - a bad mama plant. I am just getting out of a bunch of stressful grows I have finally deduced was all caused by one bad seed. I popped two of the same strain, cut clones and didn't keep track of what came from where. (won't make that mistake again).

Bottom line was that everything that came from that seed had symptoms that sounded exactly like you are describing. Nothing I did helped. And those never yielded well... Sooo happy to be done with it!!!!!

Whats the obvious reason you cant post a picture of the plant? Everyone has and does medical licensed grows so I find it odd you wont post a picture?

Anyways, cupping of upper leaves is either heat issues or you arent supplementing enough Magnesium into your nutrient profile.

You should be using roughly 5-10 ml/gal of Cal-Mag. So that should be between 150-300 ppm of Cal-Mag. Im not exactly sure what an EC of 1.3 is but im assuming its around 850-1000 PPM if you are in week 3 of veg?? So about 1/4 to 1/3 of it would be calcium/magnesium.

And you are running coco so you need to be on the hugher range because coco binds calcium and inhibits nutrient uptake of your plants for first few weeks. So i would be running the cal-mag @ 8/10 ml/gal until that goes away. More is better sometimes. I guarantee it goes away after 4-5 days if you bump up the calmag for sure. BOL

Why isnt TMV virus allowed to be discussed? TMV & Cal/Mag issue look almost identical. My chemdawg cuts that I been using for 10 years all have the tmv and it doesnt do anything to harm plants or my results.

2nd ur a little paranoid if u dont wnna post pics but get help trust me ur not that interesting and i highly doubt anyone is gonna be knocking on ur door for posting a pic of a plant that over 50% of the U.S. Is allowed to grow for medical reasons lol.

Stop buggin man noone cares about u postin a pic lol.

Sorry haven't been around for a while , anyway thanks for ya efforts...
The solution was anyway the opposite of adding more fertz to my solution...I did drain the tank filled it with water let it run with the pumps on for 30 min. after that drained the tanks again..filled with half strenght solution for a couple of days..then increased a bit to the normal strenght of only the regular basic fertilizers....the problem had been that I had read to much of all kind of hysteria around growing in coco/perlite and cause of that did add some extra magnesium and calcium....that caused the problem in the first place..
Canna Coco is made for coco (in my case 50 % perlite also)..so it has extra calcium allready..no need anymore....
Now I have an other type of dilema, my plants are getting F**** HUGE !!! they grow 3-4 cm+ a day...I did 4 weeks veg and now they been 12 days in flowering....
I wanted big plants but didn't realize that Big Buds get this big this fast...I'we been supercropping the crap out of them and " Boom "
they are back and standing tall....its the tightest jungle...today I was going to defoliate them but I took one look at them I tought no way ..it can't be done I can not get even close to them ,only few on the outher lines and that wount help much ...the net is on the way and the plants are super dense branched with millions of leaves...so defoliating I try with my next crop after these....
hopefully I get a decent yield...
last time was a bit similar overcrowding situation and I didn't do any defoliating ether...and got a record braking result anyway..
for me anyway around 3 pounds of dry product from 10 plants..
