Help and advice with flowering season and aphids

Hi guys, so 2 questions that I'd appreciate some help on

I'm 3 months in now with my outdoor grow, and my plants are looking great. Though they look healthy there are multiple huge holes in a few leaves and I have no idea who the culprit is. I do however know I've got aphids and blackflies, which I've been getting rid of with warm water, neem oil and some dish soap. It seems to work but I know I can't continuously spray as flowering will start soon and obviously neem oil shouldn't be sprayed during that stage. Do aphids eventually go with the season? I can't really prevent them or find where they're coming from so what would you guys suggest I do? Can I expect them to just disappear after a while? Autumn is just around the corner.

Another question. I planted my seeds May 24th. I'm at 14, going on 13 hours of daylight at the moment, and I assume flowering will start somewhat soon. My only worry is that the flowering period of Durban Poison is 8-9 weeks, meaning it will only be harvested around mid-end October. October the temperature in England on average is around 12°C, and could even be quite a bit lower. As this in an outdoor grow I worry for potential mold/damage from frost. Sun will also likely be non-existent, do buds need sun in order to grow properly? Could I possibly bring them inside for the final month or something?

Thanks in advance peeps

Yes your buds need sun. Are your plans in the ground? If they are I wouldn't transplant art this stage to move then indoor. If they're in pots I don't see much problem. Bug issues in flowing can be a bitch, I've used neem oil in flower but was extremely careful not to get it on buds. I have a bit of spiders on my plants this year, I let them be and haven't had much bug issues.

No my plants are in 5 gallon pots in a greenhouse. The issue then is the lack of sun that they will receive, especially inside. Is there a huge difference between buds with sun and buds without/very little?
Yeah I've heard, I've struggled with them a lot already and have read that the flowering stage is the most important stage to give your attention to. I suppose if they're still there I'll just have to try and avoid hitting the buds then.

Thanks man, and happy growing! Glad to hear the spidermites didn't cause you a big issue.

I'd look into getting some ladybugs

No, I have spiders eating other bugs. Like a predator. Is your greenhouse bright inside? Even if it's overcast? Mine is and my plants love it. Growing like crazy and its rained 45 out of the 60 days. I wouldn't sweat fall temps too bad either with a greenhouse, open it in the day, shut it at night. If it's getting cold put lots of black objects in there. The bigger and thicker the better. Black will absorb heat and hold it. It can bring your night temps up a few.

Ahhh okay yeah, should have assumed since you didn't say mites.
Hm. Not necessarily bright as it's a plastic greenish cover. I can say the same though, my plants have definitely had far more rain than sun and they're honestly quite tall. So they also seem happy in the greenhouse. Though I move them around a lot which probably isn't a good idea, but the greenhouse only gets a few hours of sun a day, so I take them out and move them as the sun moves along the garden, then put them back in the greenhouse at night.
I didn't know about the black objects thing. I'm aware black attracts sun/heat but never ever thought of that. I'll definitely do that, thank you
I'll also put a thermometer in there so I can check the temperature.
