Don’t spray those products in bud forming-end of plants stage, neem will make it taste like shit
what I would suggest is get urself some suffoil-x ( that can be used on flowering cannabis at low dosage rate till 1 before chop, 2.5T PER GAL ) + grandevo and venerate ( if u can’t afford the biocontrols get Suffoilx only ) , all approved for cannabis flower stage, don’t degrade cannabis flower, won’t damage ur terps or flavor. key is if outdoors to reapply after rainfalls and every 7days . Suffoilx is extremely affordable and will prevent pm and kill all stages of soft bodied bugs. To prevent budrot cause that’s a major issue for outdoors is look into sabf/amber biofungi or cease . That mode of action is the safe fungi will outcompete any pm and budrot and other bad molds and it will prevent 75%+ even in compact buds from getting those issues at a very low cost!
you can even drench in some non coated aspirin (grind it up) at 1-2 325mg pill per gallon and drench it in every 7-14 days, mode it will give ur plant a boost of immunity ,this also will give a huge % of sucess to no budrot, fighting disease and pest but also a overall better and healthier plant and for cost it’s amazing game changer. aspirin does same mode as regalia but cheaper ( it’s not as strong as regalia )
