Likely the beginning of nute burn. What is your PPM/EC? The first pic is the clearest sign of this.

At 3 weeks I would say the PPM would be better around 200-300. Just my opinion.

The leaf tips + dark glossy green = nitrogen overdose. BUT very light and I would not lose sleep over it. It will grow past that.

And your water PPM is probably mostly calcium and magnesium. Raise the nitrogen when the leaves begin to lighten some from where they are now. I suggest very small adds.
