1 of 4 seeds auto flowered - now what?

This is my 7th crop on this ebb&flow hyrdroton system in a 2x4 tray with 240wLED.
I switched from clones to seeds a couple crops ago.
I purchased a 1/2 dozen Skunk Glue feminized seeds. 2 failed to germinate, and 1 of the 4 took off comparatively quickly, and that one appears to have auto flowered.

I was planning on SCROG'ing and am 5 weeks in, still in veg, here's what I've got:
3 @ 12-14"
1 @ 21" (and flowering for a week).
I can tied it down to get my canopy level, but I know i'm going to be on really different flowering cycles with one plant in a tray and will share nutes.

Options:
1) pull the auto flower (finish off potted outside?)
2) let it run its course and attend to nutrient needs of other three
3) skip SCROG'ing, reduce lights to 12h and flower the remaining three as quickly as possible (too keep them closer in nute reqs); tie down the beast for an even canopy
4) ?

thanks!

This is why people who grow from seed envy people who grow from clones.

Just gotta do what ya gotta do. There is no right or wrong answer.

Plants seem a decent size. Flowering everything now may be easiest.

Why did you switch if I may ask? Cause I would love to have a source of clones near me.

Sure. I had limited selection of clone vendors for small operations... 4-6 plants is my range. The retail places were way too expensive...sometimes $25 for a juvi. The one that had strains I wanted was sketchy, and I got the wrong strains multiple times. They'd send nice photos of their selections, but then I'd pick up a bag of hurting mystery clones with thrips - in a parking lot.

I decided to try seed banks. last crop was Big Bud... 10.5oz of stoney deliciousness

Oh, and the seeds grow super thick stalks early on (pencil thick before they reach 6" high), and very hardy and healthy nodes and thick leaves. I've grown clones that were spaghetti thin at 14-16".
