Re-amending storage tote Coots mix

Hey organic people, I have a question. Last winter I mixed up some Coots mix to grow plants in. I didn't use it all, and it has been in the large storage tote that I mixed it in since. There appears to be enough soil to fill 4-1 gallon pots where I will be transplanting my current seedlings into. My question is, since the coots mix soil has been sitting for almost a year, would it be advisable to add some 4-4-4 to it, or would the soil still be ok to transplant into the way it is?

The plants will only be in the 1 gallon pots for a month or so, after which time will be transplanted into my SIPS,with a fresh batch of coots mix, if that matters. I did search the site for some insight into my question but could not find any posts that addressed it.

I would probably mix in some castings and aeration in equal amounts. Maybe 10% total and let what nutrients in there get grooving first. Maybe top dress with the 444 after transplant

Getting soil warm and moist before transplant will be helpful too.

Had added perlite at 30% of mix. But, I could add a bit more if you think it may be necessary. Also have my own worm bins, so will add some castings for sure.

I’ve found 5% castings 5 % perlite kicks starts older soils. The humus material from castings gets evened out with extra aeration.

Girls are in their new home, hopefully happy. Added some rice hulls instead of perlite. Thanks for taking the time to assist.
