The leaves went from dark green to yellowing VERY FAST !!! I did have to flush during veg because of N toxicity > Bounced back and lokked great up until now 3 weeks into flower. Added some light nutes but the NPK ratio is 0 - 4 - 0, seabird guano. Was afraid to add Nitrogen because the plant was dark green for a long time and then bam, the yellowing happened . Can somebody please help ? Seems to be yellowing from the top down > What should I do and can I save it. It's Royal Kuish from G-13 labs and was really looking forward to this starin>

Why are you feeding 0.4.0? You still need nitrogen but lower amount compared to veg. Your also not feeding any potassium so there's your problem. Deficiency in nitrogen and potassium.

I am using Fox Farms Ocean Forest and Happy Frof 50 /50 mix, was really high in Nitrogen, that is why I backed off on nutes. One plant is fine , same exact flush and situation. I guess I will hit her with some Neptunes Harvest or Roots Buddha bloom. Do you guys think the one will make it ?

I’m using a 4-4-4 at this stage. So your nutrients are lacking. They should be balanced still right now 1-1-1 IMO.

I was giving her light doses of Big bloom wich has no Nitrogen, so my guess is hit her with some Nitrogen, just hope I can salvage her. And

Well I watered with those nutes last night, should I add a gallon with some Nitrogen charged nutes today or should I wait till the next water. I'm kind of afraid to wait because the yellowing came FAST !!!! Maybe a dose of Neptunes harvest >

And thank you guys for this help, I REALLY appreciate all of you taking time out of your day .
