First Cartier Grow

Got myself a Native sun Genetics run of Cartier cookies and apple-butter cookies. There are 4 regular seeds of each that i popped into some 1 inch rock-wool cubes. After about a week they were placed into 4 inch cubes in the mean time while i get a sex test done on these plants. Today is 12/26 sent out plants for tests and they are on day 14 from seed today. First Grow so any help would be appreciated i plan to stay up to date on this grow and my struggles. Not sure if theyre a good size but i messed up nutes and p/h last week. Forsure got it fixed today so crossing my fingers things look up from here.
