Cookies kush - Sohum vs Fox Farm OF

Both these sprouts have been in their pots for a week now and I am seeing differences in how the two are growing. Since these are sprouts instead of clones my genetics will vary slightly. The fox farm ocean Forrest looks to be doing great, has a vibrant green color and is vigorously growing daily. The sohum soil seems to be Growing slower and leaves are a darker green (Maybe too much N for size of plant) than the plant in fox farm. The plant in sohum has the same amount of nodes as the other but is noticeably smaller. I have noticed that the sohum soil does not hold water very well, it dries out every other day where I have only watered the fox farm soil 1 time today (1 week) since planting it.
