Ph issue is still persisting - I think it may be a buffering issue from the GH nutrients. I partially took it out of the bucket for an all-around root check... The roots are perfectly white and fill the entire bucket from net pot to air stone, so they're not the issue. Tried adding about 1mL (total) of FloraGro to the bucket, since the label indicates it has a pH buffer. The pH drop isn't as drastic now, still dropping overall though. It may just be how this plant behaves, we'll see.
Plant still looks very healthy overall, first little trichomes are popping up!
@DoctorAutoflower, an observation for posterity in my diary isn't a complaint. Harvest timing is subjective, as well, so that's a bit unfair to call it early. I'm not trying to couch lock with this crop, so cloudy trichomes across was what I was waiting for.
