I don't think I'd swing a flowering schedule around like you have more than once in a crop. Best if you don't have to change it at all, but if you gotta do it, it's not a showstopper.

I prefer to run my flowering lights at night as the ambient air I draw into the op is cooler, but I can understand why there would be reasons to run lights in daytime (i.e. noisy exhaust fan which is less noticeable in daytime).
