My thoughts on that would be.. in theory yes it would help, but then again you might lose a couple days as she adjusts to the totally new type of light, and a different environment etc. Tough call, but maybe just leave her where she is for now, then again I've read many grower journals in the past that used cfl's for veg and then went to led for flower, or even hps + led+cfls for flower, but all of those were photo period stains I think and done as part of flower switch. I doubt auto are 'that' different about it, just that autos are on a pretty much set clock so losing a couple days maters more cause they may not be made up on the tail end.
Hopefully someone with experience can anwser. If it were me I'd probably do it (throw her in the tent with the lights up at like 3.5ft and work my way down over a couple days), but only if I thought everything else was dialed in with the new tent before hand (air handling, temps, humidty,etc, otherwise I might just finish out with the existing setup that she is already acclimated.
