Hey Wally, not necessarily lower lighting intensity but actually same intensity with shorter photoperiod...
However, I don't think you reducing from 250 to 175 would be a bad thing right now.
I think Ed had mentioned only needing about 6-8 hrs mh.. you could go longer with the t5- maybe another 2 hours on either side...
But with mh and t5, it's rarely a cause of burnt tips.. so, not sure where that's coming from.. I think some water changes can never hurt..
