Please let me know what you think, may have messed up light schedule... important!

I posted this in General Growing but I probably should have posted it here due to the indoor aspect of it all.

So I have two feminized plants going right now, they're maybe a day short of 2.5 weeks old.
I don't have a timer yet (getting one today) so the thing is I've been turning the lights off (2am) and on (8am) manually, but sometimes they've been getting a little extra darkness (the most has been about 1.5 hours which was today because I slept in by accident) so they kind of got like, 16.5/7.5..

So my question is, do you think they've already hermied or do you think I'm safe and san save them as long as i stick to a strict schedule from now on (18/6)?

i think that u will be fine a small difference in time isnt going to any damage, ur only looking at ur plants herming if they had like random 36 hours of darkness, dont worrie these plants are tougher than you think.

and 16/8 is fine i use this schedule also.
