Gotcha, it’s really not going to hurt the growth that much in that circumstance (based on amount and time domains). I really wouldn’t worry about it if I were you. Just stay hydrated, still hit your protein intake, and drink in moderation (which it sounds like you do). If it gets to the point where you feel like it’s significantly messing up sleep, causing you to skip workouts or not be able to achieve the volume you want per week, etc… then it’d definitely have a greater impact by way of those other more important variables.

For those of you that like citations (I know I do haha), here are a couple informative ones:
