light cycle

Alright so i just started growing some autoflowers and my light schedule was set at 12/12 and i was wondering if i was to switch it to a 16/8 would it mess with anything or would it still grow fine? There just over 2 weeks older if it matters

May throw them back in veg

Wait what do you mean there still in veg aren't they? sorry if that sounds a little dumb new grower but they aren't flowering or anything
