Super Lemon Haze - First Grow!

So this is what I arrived back to after vacation. My camera set up failed day one, so I was watering blind for a week and a half, just hoping they didn't die by the time I got back. In that I was successful. It looks like the plant further from the water bucket (lefty) got less water than the other (righty), so is a bit smaller overall. I looked up the lower yellow leaves as soon as we got back, which is supposed to be nitrogen deficiency, which apparently is common when not using nutes, so that's not surprising. I was only using pH'd water. It does look like the nitrogen deficiency hit the littler plant harder. Lefty had a few bottom leaves totally yellow and shriveled, righty had some yellowing and some shriveling, but not as bad. Righty also had the in tent fan pointed more directly at it, which I think caused the lean in it's trunk away from the fan blast. I had only been doing a trickle watering twice daily, as I couldn't see the plant, and didn't want to soak the dirt through, just to have it evaporate, potentially running out of water before I got back. So the night we got back I resaturated the dirt just with the pH'd water, and the following day did a proper feed, (though technically that will be week 5) I did start to notice some smell from righty when I was pushing her around to scope out the trunk.
