If your new growth is healthy then you're good. Can't fix old messed up growth.

They do serm healthy although they are drooping abit. They still have some claws but no leafs dying or anything yet. Im just observing for now..
I do however wonder if i should feed them next watering or not.. They are lagging behind now that my other plants got on canna boost, that stuff kicked them into gear in just a day!

I lost almost every fan in a crop at about 3-4 weeks because one of my idiot partners decided that I was wrong and went in and mixed everything at what the bottle said for dirt. Thank GOD it only went through once before I caught it. The crop still came out OK.

You are totally fine bro! This is not overwatering by any means. Your plant is just a little over-fed. Feed her less.

Alrite, thanks! Ill try feeding less nitrogen next feed. Its still okay to give the bloomnutes and the boost though? Theres some n in the bloom, should be enough if its an excess of n atm?You are totally fine bro! This is not overwatering by any means. Your plant is just a little over-fed. Feed her less.
Edit: what i mean is, if its a toxicity it has to be n thats abundant, right? It should be fine giving them bloomnutes if the n is low?

This plant is still bugging me, shes not doing that well. Shes been doing pretty good up until a few days ago when she crisped up, overwatering style. The soil was drying out though and alot of leaves started to die off form what seemed like wilting from beeing thirsty. I gave her water and nutes and now the next day her buds has grown and some leaves near the bottom of the plant has become soft again, not that crispy texture. However, the top of the plant looks like crap now, extremely crispy leaves and what looks like a phosporus deficiency (right?).
Its been lagging behind both of her sisters in bud development and the stretch was very short. All 3 of them have had droopy leaves most of the time though but not the crisp texture or the dying of leaves up top.
Whats going on?
Edit: Overfeeding? Ive been watering in nutes every watering, can this lead to problems like this?

It's potentially the mixing of those neuts that completely messed up your N, cal, P and mag ratios etc. And/or It could have been that you didn't shake the bottles well enough and mix them individually and properly into the main water. That can result in things binding together and being removed from the mix. That would ofc lead to an imbalance of some sort. I assume you are using synthetics as you are also using cal/mag?.
Aside from the above calmag seems to be one of those products that either works or fails miserably. If your npk ratios are not right for cal mag then it means you can't add enough cal while avoiding adding too much N. Alternatively, depending on your tap water you can't add enough mag with ought adding too much cal.
Do you check ph?, while adding in bloom ferts the ph will potentially drop more. A sudden drop or out of range won't be good either. Assuming synthetic.
what is the name of the veg/bloom ferts?.

I agree with this. Lockouts aND ph issues happen a lot more often than people like to notice. Cold you test your runoff next watering?

The reason it's deficient is that something is locked out. He stated in his first post he fed even a little extra on his last watering. If that didn't correct the issue within 24 hrs. You can definately point to ph issues.

This grow is now harvested and more than halfway consumed so i can give a quick rundown of what happened. Actually i made another thread since it got out of hand and the plants AKLMOST died. However, turned out i had severe deficiencies from lockouts, just like you guys now suspect. Most of the leafs got necrosis from P lockout and i also had some calcium deficiencies in a few plants. I severely underestimated the saltyness of the nutes and dropped nutes in there every watering and when i finally checked my runoff it was like dark urine when ingoing was only water. Flyshed each plant with more than 50liters of water and resumed to feed very lightly. They got back on track but the buds was significantly smaller than the other plants that was better off. Still yielded 60g from one and 80g from the other though and it really is the bomb. People who tried it has been really positive towards it. So dont think its all lost if you who read this go through the same problems.
Im really suspicious of my humic acid and kelp though, it comes in potash and ive heard some anecdotal report of it buffering in the soil and coco to mess it up. I might have overfed these ones too since dosage is very small in this form
Anyhow, occassional flush would have saved my ass that run.. but now i know! I also switched to coco, i think its more forgiving and easier to manage.
Thanks for the input guys, even though this grow is history i hope these threads help out someone in the future.
I used Plant magics magne-cal+, and it has N in it aswell so i see what you mean. The other nutes i used is plant magics veg-nutes and cannas terra flores for flowering. I also started the boost but got of it as my plants got wrecked. Thought id save the money for next run.

In your early posts you said you mixed veg and bloom - BAD idea!
Veg till week 3 of bloom and THEN change to bloom - no mixing needed!
NO extra P/K till that week 3!
Things will be happier that way.

Just as a warning if you missed it. Coco has cal and MG issues you should look into and it also has a greater need to maintain a smaller range of ph. Coco specific brands I assume were developed to counter the cal and mg issues but I can't speak for how good they are on the whole. You could also look into the basic hydro style neuts as an alternative but you'd probably have to get a greater understanding of the coco cal/mg issues to tackle it yourself.

Yea, i think you are right, problems started early in flowering. I thought i was putting in such small amounts of nutes that it would be good for the stretch period. Ahwell, lesson learned!
I use cannas coco a and b so its the same ratio the entire grow now. Started going by cannas schedule and its been working out great so far, switched to flower yesterday so lets see what happens..
Now this got me abit paranoid, ill look into it for sure. Ive been supplementing small amounts of cal mag and ive only had one plant this run showing what i think is early calciumdef, the whitish blotches. Thanks for the heads up!
Btw, my runoff went up to 6.7-.8 and after a flush with 5.5 water and nutes until it went down to 6.4 really had an effect on the growth. Took off like crazy.
Im just about to buy a bottle of canna flush, really want to have a weapon against overfert and ph-issues, dont want a rerun of my first grow..
