The picture is 5 day apart from D20 to D25 and it look like the flower started to pack not early like another Zombie Punch of mine but this one more trichome, i think she will bloom more week than the other Zombie Punch i have.
The top bud and the leaves this week look super healthy and spiky, bud started to get some purple but not much.
I keep her feeding at 1000-1150 at this week since it's early bloom and the size of this plant is small.
