Blackening of leaves at stem attachment and buds
    #470325 - 08/31/10 12:55 PM (6 years, 3 months ago)

Please help with diagnosis.  Thought this may be a black mildew of some kind or nutr deficiency.  Growing clones outdoors (3+ months) in organic veg garden.  Weather very hot and humid this year.  Plants growing much bigger than usual and a bit crowded. 3rd year growing.  No fert or spray just compost. Not all buds affected. The blackening is flat and smooth not shiny or powdery and only a little up the leaf from axis.  Cheers! Looking closer for a pic, I think this has developed now into powdery mildew...Is there anything to cure it at this stage (early bud)?

Powdery mildew doesn't appear black, it's white.  Are you getting temperature swings at all??  You should try to not really get us a closer picture but a clearer one.

That looks purple to me.  P deficiency possibly.  Where is the problem occurring?

as plants get colder nights, some tend to bring out pruple hues. some of mine have just started turning purple this week - its a sought after trait on the west coast

Heh, I had the same "problem"



After countless google searches and growery queries, I found that there was probably nothing wrong with her.This is the same bud 2 weeks later..
