Go for it! It shouldn't really do much as far as stressing or hurting the plant's yields. The lower buds tend to mature slower than the top buds. I would harvest whichever of the buds seem to be ready and leave anything that isn't. Let the plant go for another 5 days and check the trichs to see how they are doing. Let the plant go until those buds are where you want em as far as trich color goes. Overall doing this should increase yield a little bit as those lower buds should fatten up a tiny bit due to having the extra grow time.
