Fungus Gnats? Or actual deficiency?

Kushed - the mites are about range from 1/4 to 1 millimeter. I'd say they average about 1/2 millimeter. So just a small speck. You'll need a good lope or a scope. 40x will do to see em up close. They can have some hairs on the back side but compare to pics of cornicles on RAs. Also 8 legs = mites.

Theres a super easy solution for your fungas gnats, go to home depot and buy some play sand for $3 and put 1/2'' on top of your soil. The gnats can't penetrate the sand barrierer and therefor leave or die when buried. It's super cheap and effective, fuck using all these other products that don't work. keep it simple! Holler at me the next day after you do it and let me know how well it works :)

I've done that and still do but it wasn't enough to break an infestation. I think enough were able to use the soil around the drain holes at the bottom of the posts to keep them going. In addition to the 1/2" of sand - make sure to wash it first, I add another layer of pea gravel to stop the surface from washing out when I water. I do this for every step from cuttings in party cups to the 5 gallon pails I use for flowering.

Had the same experience using Dunks/Bits, nematodes and then AzaMax. Big reductions but enough left to re-infest. Ranged from a few to infestation, over and over. Gnatrol (BTI) eliminated the problem. Still using the sand and gravel. First 3 waterings for new soil gets Gnatrol added. Organic and effective. Hard to beat the combination.

Imidcloprid for root aphids. Yes, RAs leave "honeydew", a waxlike substance that ants like to eat.

Well its more of a sticky sap substance than a wax. And very thin amount. Im usually very careful but maybe I somehow touched one of the sticky traps to the leaves? Its a very similar substance to the sticky traps Id say.

Anyways Im going to purchase Criterion 75 WSP tonight, it has the Imidcloprid in it. So this should work? And for my next round and future grows I should just apply some of this? And maybe the gnatrol wdg?

Thanks for the tip about the sand, I've read that in several other threads too. What about does perlite help on the top layer? I have a whole big bag of the chunky stuff so if I could put it to use.


Also just to confirm that this in fact root aphids Im going to peel back the pot and check the roots. Any tips for looking for them? Ill try to take pictures if possible of the roots. And I took some more of the flyers on the traps if anybody can identify? Even tho if Im correct you can have the fungus gnats and root aphids at the same time? .... oh man....:comfort:


Thank you all for the help and advice. Really appreciate it. Truely...thank you for your time and suggestions.

From my understanding RA flyers have a rounded ass and fg flyers have a more skinny pointed ass but not the new flyers they are still lil rounded.. Bayer tree and shrub fowllowed by tri-side 7 or so days later
With a good carpet cleaning before in the middle and after worked
For my RA FG and the scary lil white mite issues.. I don't like to call them problems cause we are on the top of he food chain damn it fuck bugs NUKEM and fuck ffof unless you cook it with nemitodes and a lot ofthem first ,and after you transplant if your a hippy (no real offence intended) but chem bath, with a flush (cause amid goes in to the plant tissue)
Flush your media with phd h20 after poison and re feed with extra root inucliants along with a enzyme like hygrozyme or sensizyme from AN (before you neg rep me they sell 10 dollar bottles vs 20 somthing for Hygro) and begin feeding as usual with in 1 week unless yellowing is still going on foialer feed with diluted veg solution till roots regain their footing.. Shit I hope I made sence in all that babble but keep in note
ONLY I repeat OnLY use this in veg or you will be consuming POISON repeat POISON so be carefull never mind the 12 month after life I'm not or have cancer from it so I'd say its safe in veg only,

RB56 you are right about gnats still being able to get into the drain holes, Kushed is using smartpots so he doesn't have to worry bout that.

Those pics all look like FGs. The good thing about Imid is that it'll kill em both, just incase. You're still in veg, right? You probably don't want to use Imid once you're too much into flower. Give at least 30-60 days.

Im in flower unfortunately, but I still purchased some for my vegging plants, especially if it kills fungus gnat larvae. Last night I checked the roots and even used a scope but I didn't see anything on them as far I could tell.

Hey guys can anyone help me with how much to mix up of this Criterion 75 WSP into a gallon of water? I've read the directions but couldn't find anything specific about mixing it with water.

Also how much do root aphids affect the size of the buds? Mine will be finished by the end of the month and I'm just worried that their gonna affect my yield. Thanks for the help.

good luck

First off you're too close to harvest to be using Imid! The damage is done, ride it out. If you indeed have RAs, you should be noticing some serious chlorosis if they will affect your harvest.

Second, Imid at that strength is meant for 300 gallons per 1.6 oz packet. I have some Benefit WSP at about 1/3 the strength and it requires 100 gallons per packet. I understand they put into WSP because the powder is so fine that it would be impossible and very hazardous to try and weigh out the powder in a greenhouse setting.

And Imid is bad news for bees so I can't recommend you treat the the whole neighborhood for bugs with the extra 299 gallons, lol.

Thank you for your help. And Ya I plan on using it on my vegging plants only, I found on another thread somebody recommend a teaspoon for every 10 gallons so I guess ill try half a teaspoon for 5 then. And is it true you only have to apply it once?

And lol fortunately for the bees I don't plan on treating any other plants besides the ladies. But thanks for the heads up, I certainly don't want to be wreaking havoc on bees lol

The math works out to be 1.5 grams for 10 gallons. It should be noted that 1 teaspoon of baking powder weighs 5 grams. So you may be adding 2.5 grams not 1.5 grams. Perhaps they had the 52% stuff.

1.6oz x 28g = 44.8 grams per WSP; 44.8 grams / 300 gals = .149 grams per gallon; 10 gallons x .149 grams = 1.49 grams per 10 gallons.

As far as the one and done, I think that's more for providing a plant with protection against terrestrial aphids, not RAs. I'd do two apps about 5-7 days apart.

Try using SNS's drench with rosemary, I think it's 209 but check out their site for the systemic drench. Safe for flower, OMRI listed.
