Fungus gnats recovery

I overwatered and had a bad gnats infestation, whit fossil flour, neem oil, sticky traps and good watering practice they're totaly gone but they did a lot of damage it's now a week since i got rid of them but the two plants are not looking good, the taller and scrawny one on the left has almost stopped growing and leaves keep dying, the shorter, bushier one on the right is not looking that bad but she is slow, now i don't know what to do whit nutes because leaves are damaged by the gnats, i see sign of what it seems nutes burn but i watered once whit plain water thorow out all the flush left in the tray and didn't see any improvement, now I'm giving her just p-k less than half of what it's recommended on the bottle, maybe it's a deficiency? I'm having an hard time. Any help appreciated! There's probably a lot of grammatical error, sorry for my rusty english.

Are you sure they were fungus gnats? Fungus gnats eat dead vegetation, mulch, and fungi and don't mess with live roots.That looks more like a problem with PH, over-watering, nute lockout or similar.
Root aphids will eat your roots and inject a poison that can also harm your plants as you show. The only time I had root aphids the plants looked fine until a couple weeks into flower and then I was chasing all kinds of issues much the same as you're showing.

Once you've treated them with a soil drench maybe let the media start to dry out since the damaged root system is able to utilize less water. Sprinkle diatomaceous earth, or coco mat, some kind of covers for the pots to prevent winged insects from burrowing. Mulch with coco coir mat, perlite, or diatomaceous earth.

Have you flowered in that size pot before successfully?

To me it looks like way too little root space for that size of plant.

Sorry but the gnats didn't do that to your plants . That is all you . Poor watering habits , maybe ph imbalance, roots are unable to support the foliage above ground.

I'm a betting man and I'm going to say it went a little something like this.

They were growing like mad banshees you, didn't keep up with water needs . Roots dried out . You opened the tent saw all your ladies wilted and such. Tried to make up for it over watered the next few days . The gnats came . You burnt the new regenerating roots with neem oil .

No worries mate it happens to the best of us when new.

1st I would get rid of the dead leaves just going to cause u problems . Then come back and tell us more .
Try and answer as many questions as possible because I can't tell if your running the new battery powered super pot pots . Or using plutonium as a grow media .

Pretty much underfed and root bound. You can pull it off if you supplement feed and address microbial degradation of root binding.

Gnats are a great sign that decomposition is occurring and it is fungal dominant offering a veritable feast to gnats. Gnats are one of the worst vector violators in the garden. That is they can transmit pathogens and other pests as well as themselves to other plants elsewhere in the space.

Fungus Gnat larvae and Root Aphids look entirely different.

Root Aphids will become winged once their food supply starts to become diminished. They lay only female eggs and will often decimate a garden before the gardener is able to identify the culprit, unfortunately.

I started watering too much because I saw spots of rust on the leaves which I thought was cal / mag so I added it to the nutrient mix but it didn't work, then the leaves started to turn pale / yellowish so I increased a bit of nitrogen (always remaining in less than half of what the nutrient brand recommends) at that point I saw midges flying across the ground and realized I was drinking too much. it took a week to get rid of it. the leaves stopped dying just as quickly but not completely and the growth was stunned.

I'm growing in soil (biobizz light mix) 6.5l pots and those are both chemdawg auto from fastbuds

Yes absolute you need a positive Identification before you can treat anything.

But do you think plants can still generate new feeder roots so far along into flower?

And yes root aphids are far more difficult to shake than fungus gnats.
