Os this nitrgen toxicity

See pocs pls
What is it n how do i fix
Girls are 29 days into flower

Don’t show pics of leaves. Show the whole plant in at least one pic. In normal light. Along with the details we always ask for.

Looks like a pair of dark green, healthy leaves to me. No burnt tips or margins = no N-tox.

Being that dark green could mean they are close to being burned or it's just the strain and dark green is normal for it. A month into flower you should be backing off on N a lot tho.

Dont have any good pics at the mo lights off now
But details are
Strain, berries (thats all i know) monster clones
Veg 63 days
Flower 29 days
Medium biobizz all mix (had 1 grow through it then reused with added potting soil)
1 600w hps light
120x120x180 tent
Temps are 26c
Monkey nutriants full line
Switched to bloom nutes 2 weeks back
Sorry for the crap pics

Use the flash to take a pic when the light is off. Not even worth looking at that one which is also a large file size for my slow internet connection.

You should be feeding with a bloom formula low on N so you begin seeing older fan leaves starting to yellow while the tops are still green and healthy. They like extra Mg and S in later flowering too so some Epsom Salts are good to add to the feed.

I'm not familiar with Biobizz or monkey nutes so can't help there.

To be honest iv had no problems at all just thougjt thay looked dark im not worried
Iv already started bloom nutes
