Questions from a fellow grower:
still have powdery mildew (mainly on flowering plants in flower room). I
assume the distance of the veg plants has somewhat spared them.
sprayed SM-90 on flowering about 2 weeks ago. It “washed” off the leaves
& buds leaving a white "mildew-residue which is mainly on the lower
1/4 of the leaves on certain plants.
The PM is now on some plants,
but NOT on others. It was on every flowering plant. Now, there are 2
strains unaffected. There are not more than a dozen leaves affected on
these and 2 others which seem to have won the battle with the
application of SM-60. Just the lowest, and smallest, buds on those
plants are affected even though they grew in same pot as very affected
I have sprayed the veg with Potassium Bicarbonate,
and I am using Actinovate beneficial bacteria on the veg to prevent more
infection. I am about to harvest what I can… , then start adding some
of the veg when all flowering are gone.
How should I clean the flowering room? What can I clean with or do to prevent the new plants I add from infection?
After 22 years of growing indoors, this is the first time I have been attacked by mold & mildew.
What will this do if burned and inhaled?
the “washed” white film that dripped down towards the main stem ( &
buds) when the SM-90 was applied ( a mixture of SM-90 and the powdery
mildew) inert now?
Is it dead?
I caught it early. I have cut most of the bad off.
What can I do now? What should I do?
you know, why the heartiest, stickiest and best growing plants have
heavy PM on the leaves’ stem and bottom portion where it sticks to the
bud or stem?
