Hello.

I have two hopefully unrelated questions. The first are pictures of a plant with what I think is insect damage. The grow is indoors but I have seen gnats in the box and I assume that they are eating the plants. Regardless I have to kill them, but I just want to check that people dont think its something else causing the damage. Thanks for looking, this is my first grow and my first real question about it so far.











My second question is about my bigger plant. The bottom leaves are yellowing but it looks completely different than the other plant above. I wonder if its a lighting issue? Its very bushy and I wonder if the bottom leaves just are getting shaded?




Thanks again.

Read us back the plants diary for the last ten days.

fungus gnat larvae eat roots...if you have flying gnats, you also have eggs and larvae...Gnatrol and/or Neem and less frequent watering will kill the gnats/interrupt the cycle...

best to identify the problem correctly, first though.

>whats in the soil?
>pH of water you use?
>pH of runoff?
>what are you feeding the plant?
>how often?

i would guess the pH is out of range, but if you have flying gnats, you gotta fix that, too.

can you get a better close up of the leaf damage?

oh yeah, Welcome to ICMAG.com!!!

i would check ph and nute levels first as ive lived with black fungus gnats for years and they have never eaten my leaf matter that i have noticed.

that first pic to me looks like ph issues, the second yellowing pic just looks hungry and maybe a little overwatered.

Thanks for the comments. I havent gotten a ph level finder yet. The tap water in my area is really good but now I think I'll get one just in case.

As it turns out the damaged plant is showing some male tendecies so I've removed it. Oddly enough I caught a spider in the box who appears to have taken care of the flying gnat issue. Hopefully with removing that plant and Charlotte taking care of the flying buggers I'll be rid of that. I havent seen any of them in 2 days.

I usually water twice a day as the climate inside the box tends to dry the soil quickly(I did get a soil moisture reader), as well as mist the plants twice a day for the same reason. I am using Scotts potting soil and using fertilizer sticks, im not sure of the brand or exact description but will get it next time I post.

I read in someones post, can't remember which that blending chili peppers and water then straining, works to kill the larve and eggs but doesnt injure the plants with any chemical side effects. Has anyone used method similar to this of have any ideas non chemical that would work to kill the larve or eggs?

Thanks Sleepy for your advice also.

Thanks for stopping by and thanks in advance for any help.

Hey kubrick, I told you a while ago you needed the pH tester, even a crappy one just to have an idea around where your at. The leaves curing like that is definetly pH malfunction, you need to flush your plants. The way you do this is with a 3:1 ratio of pH adjusted water.

First and foremost go out to a pet store and buy pH nutralizer or pH 6.5 solution (which will automatically adjust your pH) Check it just incase its different. Then give you plants 3 times their bucket size. Ex: for a 1 Gallon bucket, run 3 gallons of water through it to flush it.

Problem number two, This could be a few things. Are you using ferted soil? I don't think you are, number two, they need to be transplanted! There getting way to big to be in those little cups. its very easy to do.

To transplant get your container(2liter bottle, 1 gal bucket, anything) Fill it up and dig a hole for the plant. Then take the cups and turn them upside down, hodl the plant between two fingers and tap on the bottle until the plant slides out. Then put it in the new bucket and give it a light watering of pH adjusted water,

These are a few essntials to do if something goes wrong.

I know these are the problems as I had the same ones when I started. Good luck and Ill come check em out sometime.

transplant man immediately !!! ,, those are the extreme sign's of Root-Bound

peace

Beat me too it Hallucinogen. That was what I was going to say. Also keep an eye on wind burn. If the cab is drying out the soil that quickly, then it is hot and dry in there which suggests lots of air movement (which is good) but if the air is quite warm and its constantly moving over leaves they can dry out and crisp up. Try to get the air flowing over the plants first then the light or get a second fan or just leve the doors open if you can.

[kubrickhal]

Thanks all. I really appreciate it. Should have read a little more before I started, didnt think they would get so needy so quickly.

I think GMT nailed it. I have an air filter/circulator and the radiation from the light keeps the box warm. Then the warm air is blown around and crisping them. I think I have a mad idea to fix that, I'll keep you updated if it works and I look smart.

I also got some good advice on nutes for this stretch. Pure Blend Grow, Pure Blend Bloom and Earth Juice Bloom from BOGs masterful tutorial

The Ph stabalizer I'll pick up tomorrow. Hell I might pass for a grower one day.

I'll update after I flush and repot which hopefully will be tomorrow.

Thanks for the replies

[Rodriguez]

heh i might pass for a grower one day too mate but for now im still in the torture category, you should have seen some of my learning curbs, this poor plant has put up with me like nothing else, she is hard to displease and is very forgiving, im sure she will look after you and still produce you some fine ass herb, good luck
