pH Mistake

Hi all, last night I was very tired is I forgot to adjust the pH of my water and after I watered 2 at pH6.7 I adjusted the remaining water and got it down to 6.3 completing my watering by switching back to the first two that I had already watered with the wrong pH. Do you guys think there could be any repercussions or can I be safe? I'm in my sixth week of flowering
Thanks in advance
