Hey, bro! 👋
It's fine, considering what pH you gave her in hydroponics at the beginning of flowering while she was still not a full seedling! Set the pH of your hydroponics to 5.5 for such a young age. From week 3, you can set it to 5.6 and start feeding her like an adult (for the beginning of the vegetative stage) from the second week or when she grows 3 pairs of leaves 👆
Good luck, bro! ✊😇
