Phosphorus deficiency?

Hey guys, I’m new to organics and having a little problem. First year doing a raised bed all organic, 6 plants (outdoor) Some of them are turning purple at new growth as seen in pics. Doesn’t look cold induced but something is going wrong. From what I’ve searched a lot of people suggested phosphorus deficiency or root fungus issues, But hard to get straight answer. The soil is a mix i made from local certified compost, loam, coco coir, worm castings, bone meal, blood meal, Epsom salts, miccorizae, and a few other things I forget lol I tested soil ph with a probe and it was 6.9. I also use a straw mulch. They seem to be growing great but have this purpling at new flower growth. I don’t want to blindly add top dressing until I figure out the issue. Last time I top dressed was 3-4 weeks ago. I’m gonna do a soil test in the morning anyway for shits and gigs. Any ideas? Thanks guys

Id just send in a sample just to double check your bed, that looks like MO deficiency or possibly some type of root/temp issue?

Could be a plant disease. Jimihendrix1 posted about something very similar a couple of weeks ago.

"All his stuff is from seeds.

His plants grow like weeds until they start to flower. Then they start turning Black, to really really Deep Purple, and are also deformed.

But they give no hint of anything in veg. No apparent deficiencies at all. Then Bam. When the light period outside is enough to trigger them, starting at the growing tips, they turn deep purple/black/deformed, and ruined."
