GL, I hope you don’t mind but may I weigh in on the question of
neem oil? Personally I am a fan, particularly in an organic garden. Neem is quite safe for human consumption granted it’s not in large doses. In fact before toothbrushes neem branches were used as a mean shirt of cleaning ones teeth. Yes, smoking is different than ingesting. To this end, it typically will leave no remnants on the plants after roughly two weeks, leaving a product low in any impurities. So in my opinion it’s alright to use neem early into flower, I would just not apply within 4 weeks of harvest (though applying even up to 2 or 3 weeks before harvest is safe).
123, the other thought I had is to apply silica as GL does. It will strengthen the cell walls of your plants making it tougher for the aphids to feed as well as boosting the immune response of your plants. I would suggest taking a quick look at the article I posted earlier in this thread about silica, it surprised me how much of a benefit that one element can be.
Oh, and GL those babies are stacking quickly, you are going to have a monster harvest. Let me know if you need any help trimming. With all that bud it may take days.
