Hey,
Well if you are using neem i would recommend a wetter/surfactant, i have been using neem and dish soap for years and then this year igot coco wet. Was cheap and works a treat with neem oil. I didnt think it would of helped but really did help reduce the runoff.
anything you can do to slow them down you should do. First try i.d. the pest. Then wage war, if its mites, and as your not into full flower raise the humidty, and cool the room if possible to below 16 degree C , this will slow them down and help you. I have battled mites a few times and you need to get on to them. If you can rotate sprays, as in use neem, then use horticultral oil, or pyrethrum for example. I use pyrethrum 5ec. Its a contact insect/mite a cide, and effective yet fine to use till last week before harvest. When i have used it, it will slow your flower down by a few days, but kills everything. Use a night,with fans off for night, i spray plants then fog my room with the sprayer..
if its thrips then you dont want to raise the humidty,but lower temps will help.
you could maybe get away with a systemic insecticide, but you have to use it min a month before harvest to make sure it dissipates.
Now, some people will go off on one but, you could use a product with abamectin in it. E.g., plant vitality plus(note ,also contains theramoxihide,((i will have to check the label)) , ) as abamectin isnt truly systemic, but is translinar , and will dissipates in a few weeks, now people will go off as the people who sell pvp say you can use it till the last week before harvest, but i certainly wouldn't. Its one of those do you really want this chemical in the plant, as its still going to be in there,yes it may be harmless in the plant but what about when smoked,,.?
sorry im ranting abit now.. So.
there are home made sprays but the make lack the punch needed. Personally i would think its mites, so neem, lower temp, up r.humidity, can also use pyrethrum products, hell even soap in warm water will help.
Best o luck, and you will beat um.
