Fungus gnats or WINGED ROOT APHIDS???

Your leaves aren't all twisted like mine were with the RA's, but yep scope the roots. Ask someone else first but I found when I watered in Go Gnatz they crawled out the bottom of the pot and were easy to see. Didn't kill them but it did piss them off enough to try to run. The plants actually liked it too, I saw no adverse reaction to it at all. My leaves were twisted and inverted along with the burn and curl your seeing. I'm leaning toward a nute issue from what you posted, question is... What caused it. Edit: my twisted leaves definitely showed up at the top of the plant.
Thanks guys. I did scope out the roots and they look pretty good, I think it was just because the PH in my res creeped so high! I initially PH'd it correctly but unbeknownst to me it ran all the way back up to 8.0 after a night. that's what I get for trying to run tap water this week..
And that high pH can cause nute lock out.
But what a lot of folks miss is that in flower the addition of pk boosters can cause Mg to be less available(b/c of the high K), which is the center atom in the chlorophyll ring. Then they add Ca/Mg which can continue the lock out b/c excess Ca can also inhibit Mg uptake, hence the yellowing. Additionally Fe and N are usually found in Ca/Mg additives which may give a temporary greening but the underlying Mg def is still present and will decrease yields.
Stuff from Mg/S is my choice b/c it has no N or Fe and adds the S, which is a necessary element for aroma.
The plant is suffering heat stress for sure. There may be a nute problem too, it's hard to tell for sure. If thereis a nute problem it is only minor. The heat is bad though.
As for gnats and other bugs in your roots, if you're not seeing any adults flying/crawling around it's doubtful you have an infestation. If adults are present proceed with recommended treatments.
I can vouch for Bacillus thuringiensis var israeliensis (Bti) for fungus gnats. Get powder and make up your own mix, buying Gnatrol and similar products will send you broke.
Peace
I can confirm that Bacillus thuringiensis var israeliensis (Bti) will not hurt your plants in the slightest when drenching for fungus gnats.
Always buy Bti in bulk powder form, it's a tenth of the price per unit of active ingredient compared to premixed bottles etc.
I have recently overcome a serious nute issue (lockout bad). It started out from overfeeding when using a single part grow nutrient but in the end it was all about the PH.
I grow in clay pebbles in E&F tray and my plants recovered in just a few days of adjusting my res to 6.0 before each irrigation. That was a month ago and they haven't looked back. I only water once a day now so it isn't too much trouble to adjust the res each run.
This grow will handle a rise to PH 6.2 but cannot handle anything below 6.0. I have some DJ Short Blueberry (clone), a killer Afghan Kush from WOS (clone) and some Peak Seeds BC Kush F1's (very highly recommended seeds) and they are going along just fine now that I've fixed my PH problem.
They are 15 days into 12/12 (as an experiment I'm running 11:58 on/12:02 off using digital timer) I am running at 50% strength bloom and full-strength Zyme, about to rise to 60% bloom and maybe adding 25% strength generic bud booster (I'll see how the Blueberry handle a small dose first) for the rest of the grow. I use Zyme at between half and full strength at all times (I'm sorta new to this product but after a couple of grows I'm a big fan).
My PH problem arose because I kept running my res at PH 5.8 (for the first time ever) as recommended by some experienced growers on the boards. This grow was in veg for months while I took turns at hurting it and half way fixing it.
When I settled on a diagnosis and followed the remedy diligently the recovery was quite quick.
But I have to say, from my experience and the current practice of a good friend with many years of growing in satellite pots (using clay and perlite), if you are growing hydroponically in clay pebbles you must keep your PH between 6.0 and 6.2, otherwise you are going to suffer from nute lockout for sure.
Last few posts were excellent! So now that I've done all I can to lock things up and tried adding Cal/mg further locking it up, as well as a desperate attempt to add wood ash as a top dress. I removed all the ash I could and watered with zymes, 2 days later feed, 2 days later water zymes etc. Flowers look ok but tops are pointy and slow now at 35 days. When your done laughing please tell me how to fix it. PH run off tests 6.5. Was thinking of feeding at 5.5 ph to correct. But lock out would still exist? Thanks and have a safe New Year.
Thanks guys. I actually shut down the room for months and sprayed it with some pesticide that I tried treating the grow with before and failed. So obviously they're back. I feel stupid because I should have used something new, like bleach and alcohol. Im thinking of using the orthene and pyrethrins. Steam sounds great. Do you use like a pressure cleaner for that?

Something like this. ABC is a great site for info. May not be best price. Check Amazon and their reviews. Good luck. -granger

one of the best methods i have found in controlling RA is using the help of double sided sticky tape.. carpet tape... stick that all way around your pots on the rim or near the bottom, around a flood tray to contain them.. then when you spray or flood your tray/pots they will will come out and eventually stick to the tape.. they like to move around and explore.. so its only a matter of time till they die....
also Spinosad works wonders... im trying it together with neem now...
it went all quite for 3-4 days and i didnt see a single one... i should have kept spraying..
a few have returned...

it's been said a million times before, but I'll repeat it for anybody who may not be following along closely:
Mosquito Dunk/Bits are made of Bti, relatively cheap, and widely available in big box stores and supermarkets (relative to the solutions that are targeted/marketed to cannabis growers). Probably still not as cheap or efficient as sourcing your own raw/unbdranded Bti, but great for convenience, if you want to have something in your hands an hour from now.

@ thesloppy, i take it your intentions are ment kindly, but if you read my post correctly i ask for bti powder as Old Fogey mentioned he buys in bulk...
Mosquito Dunks are not cheap by no means, especially as one cant get them in europe unless one pays the same price for postage as for the dunks.

No offense was intended or taken. My post wasn't pointed at anybody in particular, and i'm certainly not trying to push 'em on you or anybody, other than to say that they're a convenient option for lots of folks who might get the impression Bti is a specialty item. I get the same amount of nothing however anybody gets their Bti.

Hello everyone, ive had a bunch of problems with a garden i took over halfway through veg. there are several things that could be causing the death of my plants but i finally had to decide one was officially dead today and pulled it out of the pot and found a bunch of little bugs. not sure if they are whats causing my plants to die at such a rapid rate, but i spent four hours trying to wrangle and photograph them. ive got some decent photos and a video. Any help identifying them would be so appreciated. And if its obvious and i missed something previously mentioned i apologize, ive already spent several hours researching its just hard to say for sure. They are difficult to photograph, but here is the link to th video.

get some GOGNATS and do a root/soil drench and stop watering so much...

Are you sure its gnats though? i thought their larvae looked more worm like. or does Gognats work with aphids as well?
I'm pretty sure it works on anything thats eating away your root system, if aphids are present already on buds id say get some ladybugs or some sticky tape. My buddy had aphids on his indoor that was while it was raining outside so ants somehow made there way in and showed up on his buds trying to eat the aphids. looks like it could be root aphids or fungus gnats. just let your shit completely dry out before drenching your medium
