Are there any systemics that people use for mold? My grows always end up with mold in the top colas. I dont have control over humidity when growing outside in a greenhouse.

People say good things about Regalia for mildew/mold prevention, I've ordered a gallon to fight back a problem with powdery mildew I've been having the past couple of grows. It's a preventative, not a cure.
I saved a couple of plants by doing a post harvest wash with Dr Zymes Eliminator, 15 minute bath and all of the PM dissolved. Works on Mold too.

I second regalia. Another good one is aspirin, try 1 tablet (crushed) per gallon, and try feeding that to them 2 or 3 times during their life cycle. Foliar aspirin also has some good studies backing its use-I use the same dosage. There are lots of studies looking at chitosan and botrytis as well, here is one: https://www.sciencedirect.com/science/article/abs/pii/S0261219402001497#:~:text=In vitro studies showed that,also reduced germ tube elongation. They use it a lot on grapes to treat gray mold. I'd also use a biofungicide, like Southern Ag Biological Fungicide or Serenade. Lastly, during vegetative growth I like potassium bicarbonate + neem oil as a preventive spray. This all works best as part of an integrated prevention effort. If this is an issue you have year by year, I'd purchase the most resistant strains in the future as well. That's all I got, good luck to you!!

More air flow, less plants or netting to open thing up, stay on top of ya plants. I grow in a very wet foggy place i check plants24-7 an with a little 3% peroxide an careful snipping i can stay well ahead of it.

If you have power out there run as many fans under the canopy as you are willing to buy and run. When I trim off lower growth and blow air around I get no mould, when I don't I always get mould.
