My gals is under little black flies attack and lack of vitality

[Ras_d]

the reason why i have black flies in my soil is mayb i used the cheap soil or i used organic feeding (some of the protein not fully converted). I top dress the pot with wood ash yesterday to absorb to excess water in the pot so that the flies have a dry enviorment to lay eggs.. however, when i check with my gal today, my gal is droppy, and lack of vitality, also my gal‘s bottom 1/3 of the branches r droppy lack of hold ups...

I'm just not sure what's happening, i'm planning to switch the gals to 12/12 as soon as they r healthy.. please advice me what to do..


the bottom branch is droppy, also the gal is droppy and lack of vitality..

can you see the flies in the soil? they r tiny..

I don't see them but i don't like that poo looking soil either. Looks compacted? Plant is suffering from lack of oxygene without stones of some sort to airate. Tangled leaf and how are you growing it? Indoors or outdoors? What size pot is that?

Perlite

I have 4 gals growing in a 80cm x 80cm under 450w led lamp, they r in 3 gallon pots, the soil is a mix of coco coir and organic soil (soil with worm castings etc. )

Perlite

I have perlite and vermiculite, however it's kind of hard to mix them in the pot now as the roots r twisted and bonded with the soil.. if there's a way to do it please tell me how..

thanks

It sounds like you have fungus gnats. Letting the soil dry will keep them from propagating. Their larvae develop in the top layer of the soil, but they can't survive if the top inch or two of soil is dry. Some folks use a product called "Mosquito Bits" that's supposed to work well. There are other methods, too. Letting the soil dry is the cheapest and easiest method, though, and the plants like it.

agree with @LoveGrowingIt
issues with plant are more than likely from the gnat larvee..

If you have an infestation of fungus gnats (which is what it sounds like to me), you can get some mosquito bits. They work very well at killing them, but you must be consistent and use it for the entirety of their life cycle. Otherwise, you will be missing some and the process will start over. You can also get those tiny yellow sticky traps that just stick in the soil to help with them. I definitely agree that you should allow your soil to dry out some and with the next grow, don't forget the perlite or something that will aerate your soil. Perlite or a layer of sand can also be added to the top of your pot to discourage fungus gnats in the future.

I am not aware of a way for you to mix aeration medium into your current grow unless you are repotting the entire thing. I don't think that is a good idea at this point.

More experienced people may have more info.

thanks all for your replies.. may I know the chemical name of "mosquito bits" since where I am now don't have this product, i might just go look for this chemical instead.. I'm using the yellow sticky traps, but the little black flies just keep appearing..

I have perlite and vermiculite, shall I just top dress the top layer of the pot .. it's gonna be a mission if I repot and remix the soil.. cos the soil is bonded and twisted with the roots now i guess ..

I will say in my experience I have never fully controlled fungus Nats without nematodes. Now I don't f-around and find out I just place a order for 25million and keep it moving.

[Novaracer69]
