Sick Plant Plants look burnt unsure

@Woodi2 has WAY more experience than I do, and Ca is a common problem at this stage, but I think you said you have already been feeding Cal-Mag with every watering. Also Ca deficiency comes with leaf distortion and boron deficiency comes with very tightly packed flowers that look like spiraling roses.  Woodi2 may be right, but I am still betting on Mn. 

@im_sparky I couldn't see it on the bottles but they're very unclear. I'm going to look in their site now.

@woodi2 I see so I need to add more calmag and I'll just lose these leaves? 

I'm adding about 1ml per L of water. 

So 15ml with 15l or 20ml with 20l usually should I double that dose?

@silentbutdeadly224, I'd also need to know everything else that your feeding and how much. I've had this problem a couple times and it usually from getting too rammy with the PK, so if you back off the PK that may fix your problem, or a simple flush may be needed. But I don't know coco like some of the others so I don't what to say something that's wrong. But this is a  common problem at this stage of flower, the plant will be fine and will harvest fine. One of the others will straighten things out.

  @im_sparky your right on target with your assumption but a Mn defis is hard to do, a lockout is more likely the problem. From what I can tell all of the major nutrient brand contain more than enough of all the necessary nutrients and then the fact that No body underfeeds these days, so an excess is more likely than a deficiency or if it is a deficiency than it is probably caused by an excess and in flower excess PK locks out calcium first, in my opinion and from what I've seen personally because I'm just as rammy as the next guy. lol 

  You have very good intuition and a very good working knowledge of plants, I'm jealous!! lol 👍   

@woodi2 this is what I was adding from the Canna coco line and in this order:

For 15l
Calmag 15ml
A+b = 13ml
Pk 13/14 6ml

Cannazym 9.5ml

Rhizotonic 2ml

Cannaboost 10ml

For 20l
Calmag 20ml
A+b 17ml
Pk 13/14 7.5ml
Cannazym 12.5
Rhizotonic 2.5ml
Boost 15ml

@silentbutdeadly224 how often are you feeding? Any chance they dried out more than normal at any point? My feeling here is that you have an issue with the ph in the medium, good thing is it's coco so flush the pots and refeed at 3/4 your current input. Then slowly bring it back up. Make sure you have increased the calmag input at the same time you increase the pk in the feed. The pk will offset some of the calmag so you need to increase the calmag a touch at the same time to compensate. Being you were at 1000ppfd it's probably a little bit of both a ph imbalance and the plant freaking out with too much light. If your going to run that high ppfd you really need to be looking at c02, and in turn you will need to be increasing your humidity and temps to land yourself in the correct vpd range. But if it was me I would be flushing first and checking the first bit of run off for high ec and ph either too high or too low.

Back off the cannaboost a touch and up the calmag to 30ml per 20l other than that it should be sweet so I am leaning towards a ph issue.

You can discontinue the Rhizotonic too. It’s for early use to encourage root growth. By this point the rhizosphere is fully developed and does not need any more help.

See! lol I told you the Calvary would arrive, now your as safe as in your mothers arms. 🤣 lol
