Cheers SPLFREAK

So here are pics of plant, but under HPS

Whole plant went lighter and lighter in colour and bottom leaves started curling anf falling off...I also thought N def so upped fishmix to 2ml/litre and because of burnt tips now I think N lockout from overfeed.

The plants were vegged for 2 months in 25litre pots and started yellowing at 6 weeks from seed so I was so sure it was N def. Now I have no idea seeing as I upped the fish mix to double doseDSC_0313.JPG DSC_0312.JPG DSC_0311.JPG DSC_0310.JPG

Light burn.
Move the light farther away or turn the ballast to 75% or 50%

Could be deficiency but first guess is lights.

You cant see anything in picture with HPS on, retake pic under white light

Cheers for the reply Dumme...Am using a lux meter so I'm sure it's not light burn...it's also worst at bottom of plant moving up

Lookin at my own pictures I'd say N def, but what makes me doubt that is the leaves gowing brown before they fall off...is that just a symptom of late stage N def?

Hey Indacouch...No, I ran fishmix at 2ml/l from week 6 veg (when I noticed the yellowing). Because they were vegged for 2 months maybe 2ml/l is still not enough?

To much p and k, Way to early. I use nitrogen rich nutrients till about week 5 then I'll gradually switch over to the flowering shit.

I had a plant this grow that looked like that in flower just like yours. Lime green leaves everywhere. Eventually it will eat its lower leaves. I had to cut it down early because it looked worse as the weeks went on mate. Was still some killer smoke.

The only thing that I know for sure is that multiple lockout were happening. Why? No one could give me a straight answer and honestly I had 3 other bigger plants so I never got to find out.

Snap lol...Cheers anyway dude!

I have a theory (dangerous ground I know)...I had a fungus gnat problem that I let get pretty bad before using BTI to clear the larvae....maybe they ate all my root hairs leading to multiple lockout.
