I was back at the seasonal washrooms I painted in Dec. . 4 coats of Acrylic Latex Kitchen & Bath ( Co-op brand I think it is Gildden) first 2 coats where wrong color (purple), 2 more coats midnight blue. There are streaks / blotches random all over. I think more where the paint was brushed to cut in. The washroom was heated and heat on for at least 30 days after. It appears to be the last coat and also appears ‘chaulky’. Anyone have ideas what went wrong ?

You somehow picked up the "u" that fell out of "caulk"?
Paint dried too fast, due to having the heat up high in the dry winter?
Without seeing it there could be a couple of causes. Was the Glidden a contractor grade. My experience with any Glidden (ICI) wall paints...of any grade.. isn't to good
Is it darker or lighter where the brush marks are? With the dark pigmented color that was chosen, my first guess is that either the wrong base paint was used and/or there is just to much colorant in the paint which causes it to "float" causing a variation in colors
Another guess is that it is a cheap paint with low solids content...it's more likely to "lap" causing the edges and roller laps to vary
either that or with poor painting skills you're more likely to get "lap" also. Was the entire room cut in before it was rolled? was a wet edge maintained?
Was it painted before or new construction? Drywall, concrete block or ? Are the washrooms well insulated and sealed?

plywwod walls, previously painted. Not the best insulating I would bet ( 30 yrs. ) It is just the last coat that seams to be streaky / ' chaulking' , like someone spread dust on wall, but you can't wipe it off & when you wipe it some color shows up on cloth / hand. It is very random. I have painted a LOT & have never seen anything like this.
You sure it didn't freeze?

Chalking would leave a powder that would show up on your hand when you wiped the surface. It is usually seen more on the exterior.One of the causes of chalking is paint that has a lot of pigment... which leads back to my first guess in above post

the "chalky" stuff may be surfactants. google it, because i'm not a technical person. i just know i had a problem with it, too much added by paint manufacturer. also with a purple (it can be worse with darker colors.) it comes out as part of the curing process.
painted a house last summer, trim was purple. house looked great when i left. a couple of weeks later homo's call me and say paint looks like #@$! i went and looked and had to agree. no issue with body color but purple was chalky. same paint brand, different sheen. didn't matter what the substrate was, old fir trim, new pre-primed spruce, metal, hardi... everywhere it was purple.
i called parker paint and their rep told me to rinse with water. i did. nothing happened. their rep came out and took garden hose with good water pressure and you wouldn't believe the amount of sudsy bubbles that came off the paint. once i got it rinsed well, the paint looked like it was supposed to after it dried. you need some pressure, not just wiped with wet rag... so for an interior project.... hmmmm....
My guess
The paint wasn't well enough when you were doing the cut-in
but, I can't see it from my bank
not sure what you mean by seasonal washroom but
any chance someone was inside w/ bottle of champagne & it got all over the walls & they hit it w/ TSP or sumptin
Or it could be something else that hit the walls.

I have come to conclusion that the problem is condensation affecting the still drying paint. The washroom is in a park and is used from May to Sept. The roof was leaking for a few years too and that was fixed last year ( repaired at speed of government)
The 2 washrooms are 1/2 circle with a funnel 4/12 slope to front & center ( DUH!) and on a slab. Centre service room has no insulation.
I figure that the insulation, R8 ??, is not best shape and the 2x4 panels let in lot cold. We had lot in Dec. ( -20 C) So doubt that the radiant baseboard heaters could keep up.
The patterns on wall sure look like condensation / where frost has been.
It may be that the paint froze before it could "set".

I don't think it froze, I think that the moisture caused by cold wall condensation migrated through the paint, evaporated and left the pigment lying on top. Oil paint will 'spider web' blister if surface is too cold / condensation forming on surface, so I think this is the latex alternative.
Yeah, it could have been frost, condensation, drying to fast due to the heat, etc. Applying paint in those conditions is always iffy.

I think the (dis)functioning term is Glidden. For rich colors like that you have to go with a higher end paint like Sherwin Williams or Benjamin Moore, and they're top of the line products at that. I use Glidden to paint apartments for some of the cheaper landlords in my area, which works fine as long as I'm not changing colors, in which case it may take 3 coats to cover.
I'd suggest you prime what's there now with Kilz, then get the best quality paint you can for Midnight Blue or anything richer than antique white.'
Edit: I just caught the part about it's being chalky. If it is indeed chalking (comes off like a powder when you wipe your hand across it), that has to be bonded or, preferably, removed. You might be able to bond it with Zinnser's BIN or other shellac based primer, thinned down with equal parts alcohol. That should be thin enough to soak into any powdery stuff and bond it together.
