I've just had my second fatality using Neem Oil ready to use spray! 2 months ago, I had a bug prob and "cured" it with Neem oil; only after suffering a loss. I noticed the leaves began to get very dark and droopy and dried! I rinsed off the spray but it was too late! She had taken too much damage too quickly! She was a white widow Now, the same has happened to another; a white berry widow! Is this a genetic trait of the white strain? How hard can it be? I mean, spray generously to underside of leaves and stalk and branches and tops of leaves, top of soil and container with Neem oil. It almost killed my Blue Dream and Space Bomb as well as minor damage to a blue mystic. WTF!?
