I have two seedlings on day 10 after sprout. They have two very developed nodes and the start of a third. I have been watering with “zero” water with a rH of 6.4. The other day my heater didn’t shut off for some reason and heated the environment to a scorching 91 degrees for about an hour before I caught it. The plants very slightly curled in one or two places on one leaf. Not bad at all, and have still grown quit a bit Since then. My temperature is much more consistent now after upgrading the heating system. My question is, today I added a third of a teaspoon of organic black strap molasses to the water, pH was 6.4 after some adjustment, and my run off is 5.8. do I panic and flush or is it ok? my medium is ocean Forrest and they are still in solo cups until about day 14 When I will transplant to a larger container.

Just to confirm, when you say "zero water" you are referring to distilled. Is that correct? I agree with @shaw076 , just water in at a higher pH and it should drift up over time.
no need to flush just water in a little higher say 6.7 or so & itll come up
