Kind of depends on how bad the light leak is. I don't think a bit of leak is necessarily the kiss of death, just something you want to avoid. Might slow them down a little, but fix the problem and they will get back on track.will a light leak in begining of flower over the first few days equal DOOOOM!!!!!!
I understand long day/short day/day neutral flowering. I'm more concerned about the light leak and the possibility of plants going hermie. I do thank you for the reply and it gives me some hope I didn't screw up.My outdoor plants start to flower when the light hours drop below 14 hours and most are finished within 1 to 2 weeks of the autumnal equinox (12/12). I start all my indoor plants into flowering at 13/11 for the first 3 weeks ( I have observed that that and higher humidity does help with stretch). And I've have not seen a delay in flowering time with it. So to say that plants need 12/12 to flower properly is a fallacy.
