Accidentally watered with too high PH - should I flush?

[JMS757]

What would you do?
When preparing my fabric pots for transplanting, I just now realized I watered the soil (Happy Frog) with too high PH (9'ish, forgot to adjust from tap)

I've got;

(1) photo feminized OG Kush, a couple of weeks old, first pair of true leaves are showing signs of nute deficiency/lock.

(2) autoflowers Wedding Cake, seedlings that just broke through surface. I can probably scoop them out to avoid shock.

- should I flush?
- re-pot with fresh soil and proper PH water?
- start over with canna coco/perlite and ditch the soil? I've got 3-4 grows with canna coco and autopot system.

It's been 3-4 years since I've grown and now having to remember my processes.

Thanks in advance

It's fine it's alkalinity is so small and irrelevant it won't do anything.

Alkalinity decides pH power.

And if it's soil no one pHs anything the soil does that job.
