strange thing about plants is that light causes stress, but no light that means less stress (up to a point) so it will actually have endured less stress , not more. that's because the plant doesnt have that much time to fall asleep completely and wake up again completely (also stressful events for these plants lol) . Keep an eye on your babies, but dont lose sleep over this, for prolongue periods, or sometimes if this happens in the future, maintain the light schedule with any kind of other lamp if you can use your main lamps. Anyway hope this helps ! 🚀
