I've smoked some brick weed import that gave me a mild headache long ago, but I wouldn't blame that on the seeds. The seeds are a result of pollen being present, most likely from an undetected male flower a couple weeks ago. Stress by itself isn't enough to make a seed. Four hours of lights off isn't enough to stress and hermi, IMO. I recently switched from flowering during the day to flowering at night for heat reasons, at day thirty with seven strains with no hermi issues.(switched three weeks ago)
Hmmm... maybe it was a light leak then. Do you think this would do it? My tent windows weren't completely light proof I realized last night after going through a number of possibilities. I don't see any male pollen or bananas anywhere that's why I'm confused as to what caused it...
