Nitrogen Toxicity

[Newbie987]

I use a calmag plus which before I didn't realise it also has a good does of N aswell a the coco A and B so I was constantly double dosing that N

 

[Lbgrower]

You stated from seed?

 

[Newbie987]

I'm using tap water as where I am the tap was is good

 

[Newbie987]

Yeah from seed amnesia auto by kera seeds

 

[Lbgrower]

Look bro are you in flower or veg?

 

[Lbgrower]

Stop cal mag immediately

 

[Lbgrower]

What ph pen you using and where your ph at?

 

[Lbgrower]

We gonna save your trees all this stuff is important

 

[Newbie987]

I'd say flower now seen as I'm getting a fair few pistils mostly where the big flowers will be

 

[Newbie987]

My ph goes in at 6 and comes out at 5.8

 

[Lbgrower]

Your ppm isn't high what strength are you mixing the nutrients at. Like when your manufacturer says mix x- per gallon if x=5 are you doing like 2.5

It's obvious that the cal mag isn't needed and you shouldn't need any calcium with those coco nutes

 

[Lbgrower]

Do you understand the ppm conversion to e.c

 

[Newbie987]

8.5 A and 8.5 B per gallon giving a 580-600ppm

 

[Newbie987]

Multiply by 2 and divide 1000 (ppm-ec)

 

[Lbgrower]

That seems low to me

 

[Newbie987]

At 600 ec would be 1.2

 

[Lbgrower]

 

[Lbgrower]

When's the last time you gave the cal mag

 

[Lbgrower]

Your ec is good

 

[Newbie987]

I could try 9ml each per gallon to boost ec up?
