Wow I'm sorry I totally missed the first sentence. It is an auto. That is one reason why I don't like autos while others are vegging they already flower. I ran it under a 12/12 with the rest and wasn't happy with the result. Other growers have said it's best to keep it at a 18+ light schedule...
Weird maybe the low light to high light messed with it. Were your seeds from reputable bank? I wonder if you just have and autoflower. I ran an unknown seed in the past. All the other plants stayed vegging except the auto.

I then wait until the seeds crack open a bit and...
I control mine with a closed Hood. Exhaust suck fresh air from outside tent from a/c and fresh outside air. I run 600-1000watt depends and my temps stay 77-79 degrees.
Hi after looking at the pictures you can deduce a few things. If there are no bugs or signs of bugs it's probably not bugs. Reason why I say this is because one you are growing indoor. If you are anything like me you have bug screens on the intake duct and if you run fresh air from a window you...

600 usually is good for a 4x4. I'm running a slightly bigger tent. I would say a 3x3 to a 4x4 is perfect. The temp with an exhaust is easily controlled especially if you are running a HID. Kept my temps at 77-79 degrees.
Any who I can tell you now that HPS will get extremely hot in a tent that...
