1st cheap set up cupboard grow

Bottom leaves on both plants had small yellow spots. I added a half dose of cal mag to my water and the new growth doesn’t seem to have any yellow spots. Happy with the girls after 14 days....not to sure how big they are meant to be at this stage? Tried to compare to other people’s pictures, some look bigger some look smaller. Will just see what happens with these 2 as it’s only a small experiment in my bedroom
