hey guys help with slow to drink plants

hi

i have 4 plants in coco, 6 weeks veg, 11ltr pots, just switched over to flower today.

been main lining them.

2 plants are drinking 2ltrs every other day(when the pots have lost over half their weight)
2 plants are taking about 4 days to be ready to drink.

they look perfectly healthy but is this normal

My 5 plants, 2 at ~4 weeks, 3 at ~5 weeks , they're in 2 gallon smart pots, coco, and they drink 12L every 3 days. All healthy. One of the pots is only 3/4 full.

Looks normal.
