Yp.

 

Over fertilised for sure. Burnt edges, clawing tips. Really are over fed.

 

Flush the coco out FULLY with plenty of plain tap water immediately, then feed with no additives except your base A and B nutrients at a dosage of 50% for 3-5 watering's depending on how they react to this.

 

Once this is done you may be able to up the feed if they start to show signs they're recovering. Fingers crossed you may have enough time to still get some kind of finished buds. 

 

Dont feed them the Rhizotonic or Silicone ANY MORE at all, your just wasting feed and over doing it.

 

 

GV.

First thing I thought was too much PK.

 

Mix the nutes up better in future?

 

Best of luck :)

As many others have said - they've almost certainly been overfed.

 

Why are you adding all that extra shit on top of the A+B? Apart from rhizo during vegging, the rest of that is totally unnecessary (especially adding additional nitrogen) - A+B should have all you need.

 

Do you measure the EC & PH of your mixed nutrients?

Horribly overfed, soon as I saw your pictures. No doubt about it. Note how all the upper leaves are very dark green & glossy, whatever else your giving one thing is for sure :eek: ease off the Nitrogen. Excess Nitrogen in flower will reduce your yields. Note how the healthier plants (other picture) do not have the same deep pigmentation.
