White Widow Autos (first-time grower)

None of these plants smell, even the harvested one. Plant 1: Looks like 1-2 weeks away from harvest. I may wait until #2 is done drying before chopping Plant 2: Harvested. This may be the biggest-yielding one. I am hoping for 1/2 oz but it may be 1/3oz. I trimmed all the brown/dead leaves. Plant 3: Leaves all turning yellow (fade?). I will probably harvest after #1 Plant 4: I somehow underwatered and the plant almost died. I watered it yesterday and it's looking better, but pretty much all the leaves died, and there will be very little bud to harvest. I went from overwatering to underwatering in about 10 days, yikes
