No matter what you read, none of the examples you see fit your circumstance. Your neighbor can have same-same everything you have and wind up with completely different results. The examples are guidelines, only.
I do not use JP's. My method is seed-to-coco with tap water until the first set of leaves show up. Sort of. You have to be there. My tap also comes in in the 8.0 range, but I do not worry about adjusting it. Seedlings need nothing special. They just need something not horrible. Me, personally, others disagree, empirical data is still on the board, plain distilled water is not good for plants.
Another thing to consider is putting the seeds in right side up. I have never done it, but some folks cut the plugs to see what's going on.
Thank you for the emoji option. Emojis are for people who run out of words. I have lots of words. Words I haven't even made up, yet!
