Flowering stage autoflower need advice

[Theswede]

Hello! What do you guys think of my setup is there anything I could change?

4x4x6,5f tent
1mh lightbulb 400watt
1hps lightbulb 400watt
25C 50% humidity
Lights 30-45cm from the top of the plants
Fan blowing air low speed side to side
no in or exhaust (should probably fix that to my next grow but currently I dont have any problems with overheating or humidity)
The two biggest plants are 70cm and the other two are 45cm
Autos northernlight and one auto ak day 46
18Litre pots
PH 6-6,5
General hydroponics (gro, micro, bloom)
Soil with vermiculite
I think my buds are growing extremely slow there is almost no more development from the past week since this is an autoflower shouldnt the flowering process be quite fast? This is obviously my first grow so I have zero experience from growing any type of strain.

There is also an hydro grow in the background

At 46 days you are probably in the first two weeks of flower (most auto's start showing sex around 28-30 days). They look fine at this point. I don't see anything specific in what you've detailed that would point towards making a change. Just keep doing what you're doing

They are far from finishing, be patient and you will be rewarded at the end .
Btw you can use the app to post pictures easily
