nice set up and nice looking plant 👍😃 first sign of nitrogen deficiency week 6 but not too alarming as weeks go.
i recommand you use biobizz all-mix so you'll save on the nutrient bill, if you're curious check the germination week of my latest diary you'll find the custom biobizz schedule i use alongside all-mix soil and you'll see i empty my nuts bottles much slower than you.
keep it up & happy growing.
