Yellow big fan leaves (bottom) **PICS**
    #618474 - 04/16/12 10:29 AM (4 years, 7 months ago)

Second worrisome issue of the last 7 days.  I think I have finally controlled my gnat problem (hopefully)  now this:





I guess this has probably been happening over the last few days...
Its only on the BIG FAN LEAVES at the bottom of the plant. 

Is it a product of malnutrition?
Is it a product of lack of water? Too much water?
orrrrr is it those pesky damn gnats???

the rest of the plant looks great, Im not totally concerned but since this site is filled with avid growers I tend to trust people on here more then my instinct...

thanks all


**EDIT**
Plants are 4 days into flowering...

Not water at all man. 


The lower ones aren't able to get enough light penetration.  This is nothing to worry about.  Once they aren't receiving light they start to die off.

That's what I was thinking too hawk..
But I got home from work today and the entire plant looks droopy.  And I was hoping that was bc the soil was dry.  Being that I had that fungus gnat problem...

They do look a bit droopy, but I figured you were withholding water.  Keep a VERY close eye at this point.  They can go from droop to wilt real fast.  I would recommend watering before you go to bed tonight.

Ill do that.  The other two look to be okay right now so I'll let them dry some more to kill any remaining larvae. 
Ill post a pic up tomorrow with its reaction to watering.

The rest:






The only thing I noticed is that the bud spots are coming in at quite a lighter shade of green, almost a bit yellow? 
if you zoom in you can see what Im saying.

Im not gonna worry about it yet tho.

thanks for the help hawk
