Bro, nothing to worry about, I think you have a bit of nitrogen excess because of the claw-like tips. I saw in your diary that you're watering with 1L every 24H; if that's correct, then you have overwatering. Remember that you should lift the pot and feel that it has lost about 80% of its weight before watering again. The rest are doing great, good job!
Good smokes! 💪
