first time framing a deck, how do i not screw up the joist spacing?

hey all, im a newbie carpenter just started a couple months ago and got thrown on a deck build today. been in the chicago area my whole career so the wind off the lake makes everything feel sketchy up high. using 2x10 douglas fir joists like the plans say but im second guessing the 16" oc spacing with all these pressure treated boards warping funny. saw a thread on r/woodworking about using a kreg pocket hole jig for quicker attachments but idk if thats overkill for exterior. anyone got tips for keeping it square without the whole thing twisting on me? feels like every cut i make could wreck the whole job.

Don't skimp on blocking between joists, or your deck will bounce like a trampoline in no time.

Nailed my first deck solo at 22, still standing 15 years later. You got this, measure twice.

Man, I feel you on the newbie jitters, twisted my first beam and had to redo it all.

Frustrated as hell with these DIY plans that ignore real lumber sizes.

I commiserate, brother, every site's got its own headaches.

Pocket holes ain't bad for temp bracing, just don't leave em exposed.

Out here we swear by Simpson strong-tie hangers, no debates.

Damn inspectors in the midwest love nitpicking joist crowns, watch for that.

Hate when the crew rushes and skips the chalk lines.

Feel bad for ya, my first was a mess till I got a laser level.

Get a story pole for consistent heights, changed my game.

I hear ya, that wind makes sighting tough every time.

SharkBite style quick fixes? Nah, for decks it's all about solid toenails.

These homeowners expect perfection for pennies, pisses me off.

Frustrated too, bid low once and ate the redo costs.

Yeah, commiserate on the warping, soak em first if you can.

Man, I feel that twist anxiety all over again.

Same boat, my joists sagged till I doubled em up.

Every damn time, the plans don't match reality.

We all been there, just breathe and double-check.

Commiserating hard, but you'll laugh about it later.

First one sucked for me too, now it's muscle memory.

Hate those warped deliveries, return what you can.

Insurance nightmare waiting to happen if you rush it.

The big PE firms are buying up all the good lumber suppliers, screwing us independents.

Frustrated with supply chain BS making joists scarce.

Yeah, I get the newbie stress, hang in there.

Finished a 20x20 deck last week, clients loved the clean lines.

What's your beam span looking like on this build?
