Another week or so on...

here's the topped one. A bunch of the lower leaves turned yellow and fell off. I bought a pH test kit, but it's not very accurate. But from what I can tell it's right in range in the high 6s. I flushed it twice a few days apart and gave it a light feeding with Veg nutes to hopefully address what appeared to be late flower N deficiency. It seems to be doing a bit better and the leaves have darkened/perked up a bit.
