Nitrogen toxicity in flowering

rybolot · Apr 3, 2021

Hi all!

My girls are in 6th week of flowering and I just realised that they could have Nitrogen excess. I was using full Canna Coco line and doing as in official Light Feeding Schedule, Im growing under 2x450 LED lamps . Yesterday i flushed them a little, there is a net above them and i cannot reach all of them so i simply made 3 x times normal amount of ph'd water and run it through drip system.after that normal amount of weak nute mixture. Sorry for my bad grammar but english its not my first language .

Is there anything i can do to save my crop?

Thx for kind words! You gave me hope! I was thinking about cutting Canna Coco A + B completly for the moment and give them water with Calmag and PK 13/14 + Cannaboost. Do you think its a good idea? Or maybe flush them with flushing agent?

Only use PK wk 4 and 5. Canna advise wk 4 only.

But cut A+B in half , yes? Im almost sure that i have nitrogen toxicity here and im afraid of adding more N.

Give them a good flush then right after give them with half of what your doing now... nitrogen will slow down flower development

Plant some clover or rye grass,theyll eat up the excess N or just lower the N part of your mix.So if part A is then N then reduce that part by 1/2.Dont flush,Just give plain water if this is a soil grow?
