An error with on off times turned my 18/6 (light to dark) to 6/18 (light to dark). This went on for 3 days on my newly rooted clones!!!! Did I just stress the hell out of them or at that small size are they slower to react to flower....I put them back to 24 hour on. Any thoughts on hermie potential? Nirvana WW non feminized clones.
I wouldn't worry about it at this stage of growth. If it was flowering and they got 3 days 18 instead of 12 then I'd be apprehensive. They just didn't get all the light energy they could have used, so they grow a tiny bit slower for a few days.
