I need Your approval greenguys:D!

Hi!

This is my first grow. 5 ladies
strains are WW and Earl Perry. so what I am using and what I am doing:

• 1x400W HPS
• 1X400W MH
• soil
• fertilizing about 1xweek with 15:30:15 (+ammonia nitrate during veg)
• 1mx3m room
• watering once every two days
• co2 generated from yeast+sugar+h20

these pictures were taken in 6th week
longest one about 50cm, shortest about 25cm(2 were planted 2 weeks later)

pictures:

1. my lame setup
2. most beautiful and topped=2 tops
3. 3
4. interesting why the longest is most different from others?
5. a sickobut only one
6. two youngest(one got repared by attaching mylar under it)

question: i have a really bad or maybe no ventilation - 10cmx10cm holecovered with cloth. i will attach an exhaust fan but what could or will happen without it?

feel free to comment!

2 months veg + 1 week flowering

longest about 90 cm, shortest 45 cm

2 are absolutely women but about 3 others still not sure. only preflowers but no hairs.

pics:

1. all 5
2. compare
3. in front my beauty topped - 2 tops
4. the longest one already buddding
5. the longest one already buddding

questions:
why are the longest one so different and so fast growing and budding although i planted it in the same time as 2 others. is ir because of strain?

how do you think how much will i yield approx.?
