These are looking very nice. Notice how the leaves are now pretty flat and tilt up a bit. This is a sign of a healthy plant that has plenty of water and is growing.
I wouldn't increase nutes until the leaves start to lighten up a touch. Make sure to water around the plant, not under it, to encourage roots to fill the pot. Keep lifting them every day to feel their weight. Water only when the pots get very light.
Hopefully, it's starting to become more fun and exciting. They are on track to double in size this week.
