Wedding Cake [Auto, Barney's, Solo]

Well, this week saw the appearance of hairy buds, which means the flowering stage has begun. I'm continuing with the LST, leveling the height of the stems. The fertilizers will still be for vegetation, as I sense the plant hasn't exhausted it's resources for growth yet. Problems wise: A couple of times, I noticed wilting leaves across the whole bush, possibly due to LST stress or insufficient watering. There are some unpleasant yellow-brown spots showing up on a couple of old fan leaves. I have two theories about why this happened - either due to the shadow they were in or a localized salting of the soil. I've corrected both these things, but based on my short experience, I doubt it'll make a major difference overall. :)
