What a hectic week! Haven't had time to test soil pH run-off but I've started using pH-adjusted tapwater whenever plain water is called for. My Northern Lights has entered the fourth week of 12/12 so I flushed it as I usually get the deficiency symptoms starting in weeks 4 and 5. The plant is looking great! Leaves are nice lightish-green like my friend's leaves and not that sad dark-green-purple color I'd been seeing.

I'm not going to jinx myself, but I am cautiously optimistic
