New grow looking for input

This is my first time growing so I am in the learning process. I have 2 autoflowers (autoblueberry by dutch passion and auto ak by blimburn) the BB is 17 days old and ak is 14 days. Conditions are 78 to 80 degrees with light on (400w mh 18/6)humidity 35 to 40. Just gave first feeding 3 days ago using westcoast horticulture. Watering about every 4 to 5 days. Just wondering about any tips or if somthing doesn't sound right. Once I figure out how to post pictures was wondering if someone could tell me if they are looking ok.
