You water is 7 but adding nutes that are 8.5 your ph is gonna be way over 7. Have you actually checked soil ph?

yes, with cheap 3in1 meter which says ph is 7.
i hoped flushing with ph7(digital ph meter) water soil will go back to 7

Those 3-1's suck imho. I would get a good ph meter and some ph down. This will help you keep water and nutes at proper ph. Also when mixing soil there are amendments you can add to buffer the ph then it is much less an issue.

ph in soil is irrelevant. thursday was two days ago and that's when you started your thread. the plant needed more than two days to "recover" as your issue is watering. she is water stressed. you are either not watering her often enough or you are watering her too often. now that you have flushed her, i would suggest giving her a week (like seven days) and watch and listen to her. feel the weight of the container she is in today--when you notice that it is getting lighter, water her with water only over the next week.

Forget that top inch of soil BS. The best way to tell if a plant needs water is to pick it up & feel the weight. If that is not possible, use a moisture meter. If you do this, it is not possible to over or under water your plants.
Your plants are showing severe magnesium deficiency -- which can also appear if you've got root problems. Your best course of action is to spray with epsom salts & let the dirt dry out.

please notice i also said:
"feel the weight of the container she is in today--when you notice that it is getting lighter, water her with water only over the next week."
that (the weight of the container to go from heavy to light) could take anywhere from one or two days to the whole week depending on whether she is over- or under-watered.

Ill state this again....ph Is irrelevant in properly amended soil. In unamended soil it will not buffer properly. Putting 8.5 ph solution into unbuffered soil will most definately put soil ph out of whack.

my suggestion to OP is that as the grower allows the soil web to do its thing by proper wet and dry cycles, there is no need for it in a soil grow. water from the tap is fine as it is without using ph solution. a good soil grow doesn't need to worry about the PH of the soil.

The yellowing now shows you Its time to start a light dose of nutes. Something with some micronutrients.
