So..
I had some yellowing leafs.. few at first, older lower growth

didn’t think much of it but I did have russet mites last grow so I have been looking and currently no signs.. but it does have some of the symptoms

but it’s also displayed and nitrogen def .. so I added nitrogen … didn’t work

could also be mag def so I added calmag and upped my ph to 6.5 from the normal 6.2 and it’s still continuing

Im going to try a sorry of pesticide again soon just in case but and I missing something obvious?
Thanks in advance

It looks like N def to me,,, how far along in flower are you? What nutes are you using?
we’ll I thought this, these pics don’t show but there’s a yellowing between the veins on a lot before they eventually turn completely yellow

I gave them some extra n and started getting glossy and some clawing on the top of the plant so I ruled n out

only using duch pro a and b at 1 mil per litrefor about three weeks now why I have been trying to work out the problem

they are 5/6 weeks intoflower

I have just found a fungus knat. I have seen the odd one but I use tanlin on the regular so I’m surprised there even there, could this be caused by them?

interveinal chlorosis starting on the lowers could mean an Mg def, but it doesn’t look like that to me in the pics, the yellowing between the veins ends up pretty defined as the def progresses.
you shouldn’t be really needing to supp much N at all in flower…they still need it, just not in abundance. I grow organic so not the best guy to advise you on troubleshooting feeding - good luck tho!

fungus gnats are commonly mistaken for root aphids, the adult stage RA becomes winged and can easily look like a gnat. If you have been having mysterious deficiencies that you normally dont have, you should definitely inspect your soil very carefully for RA's. You will notice two little "Tail pipes" on the rear end of a root aphid.

Below is a fungus Gnat:

And here is a Winged Root Aphid:

You should definitely rule out Root Aphids if you have been bumping up the feed strength and its not fixing your issues.

The thing with an N deficiency is that once the leaves start turning yellow adding more N won't fix those leaves. Plants still need N in flower and N is a mobile nutrient so if you cut it out completely the plant will pull it from the leaves turning them yellow. They won't green back up no matter how much N you give them. But you didn't say how or what you were feeding them.
 
Whats her flowering time? I wouldn't add any xtra nutes too her if she's a 8-9 week flower..your almost done..you have enough greenery left to let her do her thing...adding xtra nutes is not the way to go this late in flower imo.. just put all you focus on infestations or root issues and keep your normal feeding schedule. On last week flush no nutes.

What are your mycelial levels at you're healthy up and down macro-micro maybe it's just not allowing you to take in the nutrients for some reason....like that dude said mobile N..... I would definitely keep pH'in them what about some comeback formula that's usually loaded with a bunch of different nitrates and stuff bring back some chlorophyll
 
Yeah I would definitely say you just need some plant food to get some chlorophyll kicking you can maybe try like a boomerang like a comeback formula ...those usually work pretty good for something that yellowed out.... also try to base out your dirt something is definitely too acidic cuz you're leave nice tough fat forming and good structure but no chlorophyll ..... thank you for giving me something to think about this place is so fun I love getting to talk to all you guys I don't feel so alone anymore lol

Hit it with fish hydrolysate ( fish shit fertilizer / emulsion ) to help get some vigor back into her . Fast acting and good for micronutrients and soil. Fast way to get some green in before it is fully exhausted.

Alaska fish fertilizer works well and i believe neptune.
