end of grow need a little help :) !!!

I'm at the end of my first grow need a lil help with insects. so, I have been flushing my three plants for about two weeks now. (I'm a week or less from harvest) and I have just spotted a tiny bug crawling around at the bottom of my tent and in the soil (just very hard to see) I'm getting lady bugs and maybe sand to put on top of the soil.

This is my first time growing and any tips will be helpful, thanks in advance.

also when I harvest I bought green light bulbs will that allow me to use lights in the dark?!? I read that the plants cant see or use green lights so that's what I plan to do when I harvest.

you can treat the top of your soil with various things like Neem oil and insecticidal soap or isopropyl alcohol & water(just the top inch or two). avoid spraying the flowers if you spray anything. definitely get a pocket microscope to check trichome color and determine actual ripeness. If you truly are a week from harvest, you don’t need to worry too much. if you check the trichs and they’re all clear, definitely apply something to be sure. not sure about green light, I’ve heard both ways, I personally wouldn’t interrupt the photo period with any kind of light.

What ratio would you use for isopropyl alcohol to water or does that really matter, like a 50/50 mix into a spray bottle possibly or what would you recommend?

Yeah 50/50 or 30/70 iso to water, on just the top inch or two
