Rep Power: 0 | | Need help having some problems
Hello all first time poster been reading for awhile i am having problems with my grow. Okay i know i have made some mistakes but let me just give you the run down. i have started my plants from seed they are about 3 weeks old now and have been yellowing in spots. my first mistake was i forgot to clean out the closet with bleach and i have noticed these little bugs i thought they were mites but they look nothing like them. i have seen a couple of flying insects in the room. so i plan on moving them to a new closet second i have been using tap water and havent been letting it stand for 24hr before watering them i have them under a 100watt mh for veg my 400hps should be here next week i havent been able to test the ph hopefully in a couple days i will get a ph tester i was originally thinking it was a ph lockout problem but then i notice the bugs can anyone help last 2 pics are of the bugs if you can see them they are tiny.

they look to be fungus gnats.

I'm unable to help you identify your bugs but, I took note of your soil and think that might be linked to your bug problem. What type of soil are you using ? It also looks like it's quite wet, is that true and how often have you been watering them? As for the tap water, why do you not fill some empty pop bottles and set them out, rotate them as you empty them.

not sure about the bugs, i cant see. hopefully they are just soil gnats, if so, try a neem oil mix, but dilute it at first. if there is a lot that means there could be eggs in the soil, if you see them crawling out of the soil a lot, a good thing to do is layer about 1 or 2 inches of clean sand on top of your soil. it will suffocate and kill the entire population. its tricky to water but you only need to keep the sand on for a few days then scoop it out, make sure they are dead. based on your description (not your pics) im guessing they are gnats but i could be wrong.
the spots on your plants look like nutrient lock out, however it could be bugs but not gnats. gnats wont do that to a leaf, they attack roots. my guess is nute lock out and you need to lower it a bit. you need to get a test kit or meter. a test kit is only a few bucks and you just add drops to a water sample and compare colors. for now try squeezing a lemon i a cup of water, or squirt some of that lemon juice, just make sure its all natural lemon, and introduce a little bit of that to your soil. it will lower the ph, you can buy ph down but you will need a meter, stick with a lemon for now because the effects on the ph are not as drastic as phosphoric acid, wich is what ph down solution is made of.
hey whats up richard! enjoy the burgers? lol
{edit} looking at your pics again, im more sure they are soil gnats, or fungus gnats, same thing. just a few are harmless but they will spread. its hard to rid them completley unless you use the sand like i told you, but keeping the population down is very easy with a bit of neem. get some neem, it has a lot of uses for your plants you will most likley need it. theres always chemicals, you can kill em all with foggers and whatnot but thats discusting

Hey i heard sticky strips hung and sticky pads turned upside down ontop of your soil can kill em and trap em for identification. And for the record, i used mg organic soil and mg perlite together on some seedlings(schwag) as a test run for my papayas and they're gettin pale and a lil blotchy prolly nutelock allready. i read the mg perlite that ****s loaded with nutes too! MG NEVER AGAIN!!! Hey H2o got any outdoor tips?

Did you mix this soil yourself or buy it in a bag ?

Rep Power: 201 | | Morning friend. I'm thinking you're dealing with a termites. The only bug I can spot in your pic, looks like a swarmer. Not that termites ain't a pain but, they only eat dead wood. |

good choice on NOT buying the mg perlite! We'll get your name changed to organicscot17 in a month or 2 and i'll explain why; its produced on a massive scale and not properly mixed. It has pockets excessive Harmful nutes, its severely infested with all kinds of harmful insects... the organic soil i mixed up myself is bug free, has just the right amount of perlite, peat moss, vermiculite and top soil. i wish you could smell my dirt compared to mg's! i say this cause i've been there man. Just recently too. i burned the heck outta my plants, had a gnat infestation, mold problem, and i've experienced NONE of these problems since i went organic... but thats just my opinion...

are the problems with mg all their stuff?
i have a grow going with mg organic soil and seems to be ok but started it as a hardcore n00b...no perlite, simply soil haha.
was going to use my last bit of organic mg soil to start my next batch and then buy some maryland homegrown composted organic soil, and apparently non-mg perlite haha.
thanks for all this info everybody

Seems last year a lot of people where reporting fungas gnat infestations after buying MG products. i think it all comes from a central plant and it all got the little buggers in it.
Especailly at this time of year there are far better choices out there people. I also tried mg organic and had a devil of a time. I know it works for some people, but it did not for me. I would recommend using any type of triple mix with a composted blend of manures and compost....take a look through the organic growing section. There have to be at least 10 mixs sticky'ed there for everyone. If you need more info, let us know.
Peace

That pre-mixed MG stuff is scary. When you have problems they are usually huge.
I personally am not a fan of adding ferts to the mix, organic or otherwise.
I know there are some serious "shotgun" mixes out there that have been used successfully by some of the top growers, but most of us are not "top growers" and don't have the experience to recognize when things are going wrong until it is too late in these types of pre-mixes.
However...some folks have that "Mad Scientist" bent and just can't help themselves...LOL
have fun, folks

Don't forget to add something to the soil which will give it good drainage.
Fox Farms has that giant perlite (I stay away from the perlite that is basically powder, worthless, IMHO). Fish stores sell lava rock (which is ph neutral, holds oxygen and gives roots great places to hang onto and collect the o2.
My soil mix is probably 30~35% big perlite and/or lava.
Also, I put a coffee filter at the bottom to handle runoff and on top of that I have a bed of at least an inch of the perlite (it's a root thing).

Yes, thank you Grandfather. I always add perlite, without anything else in the perlite. A total of 40% at the max, but reduce it if there is already some in the promix you buy. I have never tried the lava rock, but I just might now, thank you sir.
For seedlings and clones, you do not need anything else in the soil until they have grown several new sets of normal leaves.

Avoid the stuff which is colored.
