Green house seeds contest

Pretty nice so far!! The only thing I’m wondering is do I need to add cal mag?? Anyone know plz msg me.. But so far these little babies showing great growth. The colour is a little on the lime green side but they are growing. I’m super excited to be in this contest! The nutrients was easy to measure and add to my coco.. I didn’t do full strength due to I’m thinking a 4 week veg, so I figured go half and I can always add. Good luck everyone
