Is this to be expected ?

My buds are tiny on day 25 starting to see frost and some red hairs

Day 25 from flip or first sign of grouped pistils? Its fine watch it will hit growth spurts be patient weed is not for the impatient, she will tell you when she is ready!

Day 25 from flip all my plants look the same tiny buds is that ok for day 25 I'm feeding them oneness from humbolt nutrients soil mix

Yeah your good! So you are theoretically day 12-18 keep track of the day you see them and your flip day.

Ok thanks man appreciate it
