Messed up lighting schedule

[FDXRN3321]

Hi guys my DP Colorado cookies are about 8 days since breaking ground. I've messed up the lighting schedule twice now... The lights are on a 20/4 regime (10pm They are off untill 2am) and once I forgot to turn off the lights until 1:30 am and just today I forgot to turn the lights back on until about 5am so they got an extra 3 hours of darkness this time.

I have no experience with autoflower. I'm wondering if this will stunt the plants growth? Does a solid lighting regime matter that much for autos?

I do realize I need a timer I purchased some online but they don't have the 3rd prong for the ground so I can't use them. I have new ones coming soon.

Thank you.

Light timing doesn't really affect autos so you will be ok.You can buy a three prong adapter cheap that will plug into your timer.
