Have I got mold??

[Have a Cigar]

The picture is of my White widow leaf, 3 weeks into flowering. I think the lighter brown spots are mold and the darker littler spots are from a deficiency, I also think it might have a mild nitro def also. I cut a few leaves off the bottom-Middle that had these spots on them, but whatever it is is still spreading slowly. Could it be my humidity levels? It gets kind of cold at night and there is water in the air because of the moist dirt. Any suggestions appreciated, thanks.

Yikes.
Okay... pale lower leaves in flower... not terrible.
Worry about those black spots first.
First off, go get a bottle of Serenade right away. It's an organic fungicide made of bacillus sp. bacteria that is perfectly safe to use in flower. Give your soil a good drench next time you water, using it as directed. That will help get the mold under control if that's what it is.
There's also the possibility of a viral infection, in which case your plant is cooked but youmight be able to limp it through flower anyway.
In the meanitme, Si, Ca, and K help your plant's immune system. A high K fert and some Silica Blast will be helpful.
Low humidity prevents mold. If you have LEAF mold, but rot is a DEFINITE. Get your %RH down to like 30% NOW.
Get your temps up in range too: D70-80 / N60-70.
urrr good luck... post back how it's going

Oh also if you have more than just that one plant, and you can isolate it from the healthy ones, DO IT!!!!

:( poor plant looks like its riddling with aids :p lol

[stinkyattic]

I'd say leprosy or the Pox.
You can't SEE AIDS... and I don't really think AIDS is a 'lol' sort of topic.

wish i could help, and yeah aids isnt a joke, i can see the humor hes trying to instill, try a lesss touchier subject other then aids

what about a flash freeze? set it outside for a few minutes and bring it back in? u should be able to go to ur local hydro shop or gardening center and purchase a mold/mildew spray. colder weather restricts mold growth.

[stinkyattic]

Not practical.
The temps required to kill mold AND its spores would kill your precious plants much faster.
Trust me, just use serenade. Or whatever fungicide you find that is SAFE IN FLOWER. You have to get into the soil too to kill spores.
After this crop, empty out your grow room and bleach the fuck out of everyting, including your equipment.
Colder weather also slows plant growth.
The only time I would suggest using cold as a tool is to
-prevent mites from breeding while you are doing a treatment program to kill the little shits
-bring out the maximum purple in a purple strain, if purple is your primary goal.

Thanks stinky, do regular hydro shops usually sell serenade? If not can I pick it up at home depot/lowes? I'll find a way to raise the temp and I'll put a dehumidifier in the closet for now, im saving up for a CFM fan to exhuast some of that shitty moldy air out.

[stinkyattic]

They have it at home depot, walmart, most grow shops, and every garden center everywhere... look for the active ingredient, bacillus subtilis.

Yeah fresh air flow is crucial... a fan... ANY fan... just find a fan!!!

I love Serenade. Also a big fan of Don't Bug Me. Go Stinky!!!:D

Ooook, so I got the serenade at the hydro shop, and there is a fan running full speed pointed upwards 24/7 for now, it used to be only when the lights were on. I also got a hygro/temp meter and the humidity is around 40-43%. Should I spray the serenade or mix it into water, if so, how many tsp per gallon of water? thanks.

Mold likes cool dark places. Think about something going moldy in a fridge. Stagnant air at night is bad! Your humidity is perfect around 40%, if you can prevent it from going higher that's good. Hope you get things sorted man. :jointsmile:

I think its under control, I sprayed them down with serenade and left a fan on 24/7 and stuck a dessecant dryer in there. The humidity ranges from 39-43. I also watered them down with bloom ferts.

Should I spray the serenade or mix it into water, if so, how many tsp per gallon of water? thanks.
Both.
The directions should be on the label.
Spray it on the lower leaves and stem.
Add it to the water to take care of mold and mold spores in the dirt.
