even a cut from someone else's garden will be different then from seed. the calmag is for the coco not the plant. your coco is probably causing issues because it doesn't have enough calcium to allow proper CEC , therefore it's stealing it from root zone to supply itself, once you get the calmag in it may rebalance and you will have proper CEC

Lol light above outside the door as flash on the camera phone has a mind of its own.
Yeah know every seeds gonna be different. Thing is though this blues strain I got cuts of it from two different plants and literally all seemed to handle the N toxicity worse. Can't say its a fussy strain as I know I was too keen with the nutes. I don't like that word "may" lol . I am hoping the cal/mag sorts it out. No good giving the plants a spray feed with it then? I thought the coco would be alright now as it got flushed to get rid of the excess N. So now should be fine and able to get the correct amounts of nutes up taken. Not a problem like I will water the cal/mag in the coco. Just read online the foliar feed with get into the plants quicker.
They aren't perfect by any means but I do feel they are looking better since the flush. I deffo feel that's the nitrogen toxicity taken care off. Now sort the deficiencies out and should be ready to flower. Thanks a lot for the help. Will carry on posting so others can use the topic for future reference if needs be.

I only say "may" because your not sure of the source of your problem yet. we have to eliminate the different sources 1 at a time. not having calmag will cause a calcium deficit for sure we know this, but will it change your other deficits perhaps not. those may be from an imbalance in macros NPK and nothing to do with the micros cal and mag.
so let's fix one thing at a time, satiate the cocos need for calcium and you may achieve balance

again feed the coco the calmag do not foliar feed or your coco will still not have any calcium in it.

Buffering coco is accomplished by soaking it in Ca and Mg. This allows the cation exchanges to take place prior to adding plants. Simply soak your coco in a solution of Cal/Mag water and the exchange sites will release their K and Na cations and lock onto the Ca and Mg. When the cation exchange sites bond with Ca and Mg rather than Na and K, it is “buffered”. The bonds that hold the Ca and Mg to the sites are very strong and cation exchange will largely stop. This means that all of the nutrients that you add to the water will be available to the plant at the ratios that you provide them.

I thought with excessive N washed out they'd now be able to uptake the calcium provided in the nurse without a problem. Just they might need a bump if you like with the cal/mag as they haven't been getting what they need due to the nitrogen toxicity. Hope it makes sense what I'm trying say in regards to how I view it.
Not possible to just identify the deficiency without having to piss around with stuff and seeing if it changes anything? I thought the plants was showing calcium deficiency and Mg. So thought the cal/mag would sort it. Given the plants bit of a boost then be able to just carry on feeding normal nutes as usually do. Seeing as now ain't too much nitrogen so they can take up the notes without anything being pushed out by toxicity.
I will water the cal/mag like you say of course. Hopefully that's the issue sorted lol . If not what would be the next step? Or have to wait and see how that has them looking? Proper desperate to flower them as timing could be an issue.
Still feel the branches aren't growing how they was, seem thinner. I had an issue once before and Epsom salts done the job. With that though the branches grew woody. Only mention it as once the issue got sorted they went back to producing as normal. May be the flush will have sorted the branches here feeling thinner but too early to say yet n might take bit longer. I dunno lol and they look fine but yeah can't just pinch the plants branches and get that hollow snap feeling like before. Anyway cal/mag is here tomorrow hope it comes early.

yes feeding the calmag might help with the antagonists, the N tox is also a culprit, you got two things going on at once. sorry if what I say doesn't make sense

Don't be sorry you've been a great help lol thanks.
I agree there is more than one thing going on. The N toxicity caused issues with other nutes and "pushed em out". That's putting it in an idiot's terms lol . I just thought the light feed flush would have taken care of the nitrogen excess issue in the coco. Now the coco is sitting with the correct balance of nutes although low but can bring it up slowly over next few days. But the plant hasn't been getting whatever nutes it has a deficiency in. So would be fine to foliar feed the plant to give it some extra of what its been unable to uptake.
I am gonna water the cal/mag like you say. What I just said above those does that make sense and is it right or wrong?

Quick update, ladies with problems all got a feed with cal/mag. Saw no improvement and tbh looking at them pissed me off. So you guessed it binned them lol . All apart from 1 which looks alright. Got that with the 4 other strain all under one light. Gonna put them into flower tomorrow and just look to crack on with it all asap.
Lesson learned for me anyway simple mistake with being too keen with the feed and caused more headache than its worth. Only even done that because the stupid problem of giving em too much water to soon. Then them looking hungry where wet for too long. Anyway cheers for the help I just can't be dealing with fucking around with em anymore. Sooner this lot is finished the better.

It got mentioned on here and I know I binned the terrible looking plants. Well guess what. The other strain which didn't look as bad has started giving problems.
I think the issue is a phosphorus deficiency. The big give away for me is the new leaves are growing really small. That's first thing that was standing out. Branches have gone really thin like I mentioned, wouldn't be able to pinch these. Also really weak like you bend one and it will just stay in that position. Plus also red petiole. But yeah I am thinking it is a phosphorus deficiency as only one I've seen which says can cause the plant to grow small leaves plus the leaf markings and red.
I can't continue with these flowering if they don't improve as I know the yield and bud will be shit. So gonna increase the feed a little to get more phosphorus into them. The feed was cut back when I flushed them. Increase it slightly and order some raw phosphorus. When that comes ill hit them with that and fingers crossed the new growth will not be tiny leaves and the branches will go back to how they was.

My phosphorous gets here tomorrow, finally. I tried cal mag like others advised on here and it did nothing. I have also read phosphorous could cause small leaves? My plants look like they are gonna yield really bad. The real issue is the branches have all gone thin and the newer leaves are all super tiny. I have checked my ph pen and calibrated it, was on point anyway.
Hopefully this will sort the issue. Just want the stems and leaves back to normal. Apart from that they look alright. Is weird to see some problem actually able to manage to shrink the stems.
