Hey, why are some stems of the leaves purple? pH has always been 6.5... you can hardly see it in the picture, but this one leaf is also swirling weirdly... I give 100 ml of water per plant every 24 hours.
No worries, I would still be careful with the water. I always water in a circle with a 10-20cm radius around the stem so the roots can get what they need. Otherwise, I wouldn't worry too much, it looks good. The color on the stems could also be due to the strain. But that's not a big deal. Your ladies look nice...
