Reverse osmosis in Fox farms soil

Normally when I grow with synthetics which is how I've always grown I've just filled buckets with water out of my bathtub, let that water sit for 24 36 48 hours just however long at least a day. Then I whip my nutrient solution and feed
if I use reverse osmosis water do I need to let it set out and is there a reason I shouldn't like are those they're micronutrients getting filtered out that I need because I'm in soil and not hydroponics I'm thick the soil is going to be Fox farms ocean forest and Happy frog with perlite
then the nutrients are going to be the Fox farms basic trio veg tiger and Bloom with chiching.
it's kind of a pain having all this water sitting around evaporating off so that the chloramines gone and a lot more convenient to just go to the store fill up a 5-gallon jug pay for less than $1 and just make my solution fresh each time sorry for the lack of punctuation I'm doing speech to text while I do chores around the house

You're not removing the chloramine by letting your water sit out. Chloramine is chlorine bonded with ammonia and will stay in tap water for quite awhile. And not all RO systems will remove chlorine, chloramine, or ammonia so make sure if you get one that it does. A quality carbon water filter will remove what you're trying to get rid of.

They put chloramine in the water where I live and I just use it straight out of the tap. Have been for years. Plants don't seem to care.
