I'm doing my first ever grow in a minimalist fashion, not buying too much crap and keeping what I buy to what's available locally at the shit Wal-Mart and Lowe's type stores that are around here. I'm about 5 weeks in from seeds. These have been vegging under 24 hour 2x60W (300W incandesecent equiv.) CFLs (and a 300W equiv. CFL is a weird thing to see because the "Compact" really doesn't fit) and 1x23W "daylight" CFL until one of the big CFLs burned out a couple days ago (probably not meant to hang upside down) and I replaced with another 23W "daylight" CFL.

I've two trees, indoor in Miracle Gro organic choice potting mix. One of them, on the older leaves, is exhibiting yellowing and brown spots. From my limited reading I suspect a nitrogen deficiency as these leaves were around before I fertilized (10-10-10 plant food) and this has only occurred on leaves which also have a red stem. Younger leaves look fine so far and are on green stems. Overall the plant looks pretty decent.

But I don't know what I'm doing so here are photographs - one of the whole tree, one close up on the worse affected leave including the red stem.

Thanks everyone.
