Problem with brown and dying leaves on one side of plant.

Help for sick or damaged marijuana plants. Marijuana growing pests, diseases, nutrient problems.

I am having a bit of a problem with one of my plants. I have 3 plants going.

Two of them look good but the third one is having problems.

From the pictures you can see that one side of the plant is growing fine but the leaves on the other side of the plant are turning brown and dying.

I have included a picture of one of her sisters that was planted at the same time and is doing fine.

There were some additional leaves that had the problem but I have cut them back to get rid of the brown.
However, the brown came back and just continued to consume the leave after I cut off the bad part.

I am currently flushing the system with clean water in hopes that this is nutrient burn.

Any help would be greatly appreciated.

Here are the specifics:
1. Pot size - 28 gallon tub with 12 gallons of water in it.
2. Growing medium - Hydro
3. Watering schedule - change water every week
4. Feeding Schedule - Advanced Nutrients 3 part. Bloom/Grow/Micro ppm is 650 to 700
5. lights used and how far away - MH overhead and two compact flourscent on the side. All lights are 2 to 3 feet away.
6. PH levels - 5.6 - 5.9
7. Age of plants 2 weeks in hydro / 3 weeks from birth
8. Stage of growth - veg.
9. Strain - Supergirl Feminized

nope-- you got a disease there hun-- from the lower leaves getting & staying wet...
We lost a bunch of seedlings and clones to it.. it just keeps spreading..
1st-- get the infected one as far from the others as ya can... Then
spray the plants with 3-in-1 fungicide and wait a couple days.. i the infected one looks the same.. spray her again..
if she is worse, and the others get it too.. spray them again and kill tyhe infected one.... loke I said-- it just keeps spreading and is very hard to get rid of!
Dampness in a warm room is a contributer-- so watch the temps and humidity real close!
No need for revenge, just sit back and wait.

Can you give a a brand of 3-in-1 fungicide that is good to use.
Is this something I can pickup at a garden store?


LZ - would pulling the leaf off not help?

Well I bought some SureFire 3 in 1 Spray and now I hope for the best.

It always hurts to loose one!

Thanks for your help

check the ingrediants-- should be NEEM oil and Pyrethrins (sp?)

And no-- when that small they need their leaves, AND it spreads by spores so the rest of the plant is allready exposed... just gotta hope it doen't spread to the others...
