N tox? Canna coco nutrients in coco/perlite

[monkee]

Hi!

Think I might have some N tox going on ?.

Fast Buds Gorilla Cookies Auto


Day 54 since cotyledons opened

Medium Coco/perlite 70/30 in 3 gallon fabric pots

Nutrients
Canna Coco A+B
Canna Cal Mag
Canna Rhizotonic
Canna Cannazym
Canna Boost

Been fertigating 3 times a day with a total EC of 1.2 with about 20% run off

I have soft water ( just shy of 0.2 EC) so I add Cal Mag till EC of 0.4 then A->B->Rhizo->Zym->Boost and my final EC is 1.2
PH when fertigating ranges from 5.8-6.2 ( mostly around 6.0)

RH is around 50% and temps are around 25 Celcius durings lights on ( about 20 Celcius lights off)
DLI is around 40 at edges and about 50+ i center (Using Uni-T BT lux meter in combo with PPFD android app so values are not 100% ofc)

I read on Canna Calmag bottle that its 6% N (6.0.0)

Since the only way to lower N is to eliminate Cal mag ? or what sould I do ?

Hello yes they do look very green to much N i grow with canna nutes i never feed above 600ppm or 0.9EC and i use pro cal by green planet as it only has 2% N init. :smoking: :smoking:

So as I'm about to mix a batch (I mix ferts for 3 days at the time) would it be stupid to exclude the calmag for this batch since A+B do have some cal mag in it (as I understand it) ? That would put me at EC 1.0

Hello i stop using cal when i go into flower if your coco is bufferd. yea will be fine missing cal out as the plant is not asking for it i only use cal when its needed not every water/feed :smoking:

Cheers m8 I will skip cal mag in this batch. I did double buffer the coco and think I got the EC run off in sutable range before each up potting but this is my 1st coco run and all these coco stuff is new to me but I'm quite sure I had a EC below 1.0 on the buffered coco befroe I did my final up potting ( transplant)

This is my feed with cana i only use upto 450PPM in veg and flower 550PPM max and i allways use canna pre buffed coco save all the guess work :smoking:

Did a closer inspection this morning and this is what I see( only on 1 place) and this is Calcium deficiency right ?.

Guess I'll have to go get me a bottle of GHE Calimagi as it's 1/0/0 compared to Cannas Calmag 6/0/0.

How should I act from here ?



Thanks
