Grow Mediums nitrogen toxicity, any quick fix

[TheJollyDankman]

hey everyone,
im new to growing but I've done one other autogrow in coco before that went without problem, but now ive got 4, 2 week old heavyweight fast and vast autos but only one of them has a N toxicity problem, they have all been fed the same amount of canna AB nutes + bloom calmag and i think ive figured out that it is due to me using the bloom calmag which is 6.8% N, in the last couple days ive stopped using it but that one plant is still showing signs of N toxicity, i have searched on google and only found things that say just reduce the amount of N but i have and still i got signs of N toxicity, if anyone could advise me what to to fix this, the mix is roughly 1 part perlite to 2 part canna coco, any and all help appreciated thanks

Flush them with plain ph water and hold back on the nitrogen.

2.5 ml/L at 14 days is way to much.. i gave mine like 1 ml/L still then at that age "My 2 cents" think you gotta tune it down abit my friend :Sharing One:

thank you mate, one final thing, im going by the canna coco grow guide, but should i just take what is on the bottle start at quarter strength and work my way up?

 

[RebelRoy]

i`ve been using that guide aswell..but be sure to start on a lower dosage of what they say..specially on autos.. they dont want it as strongs as a photo strain. and from there work your way up by looking on signs from your lady

they want you to never feed lower then 600 ppm.. but i run my nutes true on 300 ppm the very first time ...just my 2 cents :Sharing One:

how do you like your new avatar buddy? xD you can change in settings if you want i like a friendly goat face ^^

get a journal up and running so we can follow your grow. that way its easier to diagnose any problems if you should have/get any
