I have the same issue..... But, I don't think it is the grower.... Not infestation, but, there is something nibbling.
8 days into 12/12. I've Neemed the last 3 weeks... I will once more before buds start forming....
Maybe Friday's Neem took care of it..... Praying....
I pruned today... removed all the lower branches... took them in a different room, inspected everything... found nothing..... even got my loop out for a couple of spots I did see.... but, nothing really.....
