Botrytis On Leaves

Recommended Posts

Well I was hoping I would never have to post here again.......  but here I am :( Some of my poor Snow White Kush leaves have been showing some signs of what I think is Botrytis, or Gray Mold. 

 

Plants are 16 days into flowering in 7 gallon soil pots.  The temps have been in the mid 70s lights on and dropping to around 68F at night.

 

I believe this is directly related to humidity.  I have been trying all sorts of ways to get the humidity in check during lights off using my 2 gallon dehumidifier (which fills up and turns off within 8 hours on low).  When the dehumidifier is running on low near the intake for the closet I can keep the rh around 55% at night, which is much better than the 70% it spikes to without.  During the day the rh is around 40%.  There have been a few nights where I have forgotten to turn the dehumidifier on, or it filled up and I forgot to empty in morning causing it to turn off, or I spent the night away from my house and wasn't there to turn it on.  

 

Last night after discovering the Botrytis I went out and purchased a hose and connected it directly to the dehumidifier and ran it into a drain.  Last night is the first night I have been able to run the dehumidifier continuously on high without worrying about the bucket filling within a few hours.  I am hoping this gets the humidity down further and I will check once the lights come on today at 11am.  

 

I spent last night cutting off any infected leaves I could find.  It seemed to mostly be on the largest fan leaves.  Things are SO bushy and full on both plants that it seems to make a perfect place for these to grow.  I took off lots of leaves last night and probably could have taken off more but I was already pushing lights off back by 15 min. 

 

I have been noticing this stuff for a few days but I thought it was just the leaves naturally dying off or maybe that I splashed them with some tea.  Then it started to look kind of like a porous rust on the leaves.  Once I took some macro pics of the leaves I knew something was very wrong.  Although the pics make it looks much worse than it does to the naked eye. Wish I would have done this earlier.

I wish I would have taken a pic of the late stage but I forgot... so I stole this pic from another site showing a good example of what some of my underbrush looks like.

Will lowering the humidity and getting the temp above 70F be enough to combat this?  I have read that GreenCure can help eliminate gray mold. 

 

Peace

After some discussion last night I think I may just be freaking out a little bit.  Most of this is probably nute burn from all the tea they have been getting. 

 

I was able to get the humidity into a nice zone last night by running the dehumidifier directly in the bathroom where the grow closet intake is.  Last night during lights off the highest humidity was 42% with the lowest 34% :)  It's kind of a give and take right now because running the dehumidifier in the closed bathroom makes a good amount of heat. Temps were 82F lights on 75F off last night.  The way I see it is better to have it a little hotter than humid. 

 

In my panic I cut off lots of the fan leaves.  Hopefully this will benefit me by increasing the airflow and letting the light penetrate a little deeper.  After I spoke with the great staff here I kind of felt like Brittany Spears after she cut off all her hair..

I will keep an eye on everything but I don't see any more of that white stuff on the leaves.

During lights on the room has been reaching 80F at tops of plants (72F at roots) and 31% humidity.

 

During lights off the temp drops to 73F and humidity maxes at 43%.

 

I have been inspecting the plants and have not seen anymore of the white stuff or much more burning. I'll throw I some pics when lights come on.

Wide temp changes will hurt ya, and 80 at the canopy as you know is a bit much.  Id keep it dry as steady as I could, Your humidity is great.

 

Does anyone have any advice with the above pics?  I think some of it is not mold related and never personally had this problem...

 During a chat night KarrMcdebt and I went over  nutrient overfeeding and think perhaps we found our cause. so yes this was discussed
