Hello,
using a 2x2x5 growbox with a 400W MH for now(switch to HPS during flowering, which is this week).
I have
1 super skunk
1 Auto red poison (fast buds)
1 blue God
1 Northern Express (supposedly Auto as well) (fast buds)
The super skunk is doing really well,

they all have the same soil
the Northern express (in hydro) started off slow with PH problems but is now doing much better, pic below

It still hasnt started flowering yet (on the website it says 12-18 photoperiod) you think it is still too young or should I switch to 12/12
Auto Red Poison.
Started off well i may have given it some nutes at the beginning that may have stunted its growth but it feels like it is in the late stages of flowering although it is only week 4.
temperatures in the growbox range from 28 to 31 degrees (cant do much more as I live in a hot area)
have very good airflow with 3 fans blowing over them, a 200 CFM fan exhausting the heat out and another fan getting cold air from the house.
It is very small compared to the others
week 1

Week 2
week 3

The buds are already purplish but I really want to know why its so small.
also there are really small black bugs that are around in the soil, i've seen them in the Auto red's soil but im guessing they probably infest all the rest.
please help
