Brown spots! Help!

Okay, maybe I'm being paranoid, but I've had too many passis on the brink of death and want to nip this in the bud if its within my power.

My brand new Lady Margaret, after a week in my care, is starting to show brown spots on her leaves, and some along the leaf edges:

We've had heavy thunderstorms this past week, but after over watering several passis to ill effect, I made efforts to keep this one sheltered. Checking by touch, the soil in the pot several inches down is moderately moist, but not damp. She is on a porch where she gets sun until about noon, then shade. Temperatures have ranged from the mid 80s to the lower 90s during the day. There are no insects on her that I can detect--my incense is literally crawling with gulf fritilary caterpillars, and I found six newly hatched caterpillars munching on my struggling Amethyst the other day (which is why I've been keeping a *very* close eye on Lady Margaret. Thus far I haven't even found an egg).

She has several mid-sized flower buds, but dropped one since transplanting, which I attribute to stress. A few leaves have dropped, but it's been quite windy of late. The leaves are a brighter, lighter shade of green than, say, incarnata or incense or caerulea, but I don't know if this is normal for this hybrid or is a symptom of something else... lack of sun? I dunno.

It is planted in a mix of run-of-the-mill potting soil mixed with moderate amounts of sand, pearlite and spagnum moss. It is planted in a 12" pot.

To the best of my admittedly limited knowledge, she should be thriving. But I've had others go into slow decline, and if this is what Lady Margaret is doing now, I want hep from the experts while she's still healthy and (mostly) green! :-)

RE: Brown spots! Help!

I have a ligularis that has spots like that on its older leaves, and I think - for mine - they happened when it went from 60F to 80F during the day in under a week. I actually used to have a lavendar lady but some fungus or something spread from a strawberry plant it was sitting by and killed it. But, I'd say it doesn't like the spagnum moss you have with it (is it just sitting on top to help stop water evaporating from the soil or mixed in?). When I replanted my lavendar lady, it had roots growing all through and around the styrofoam at the bottom - so I'd imagine they don't like being right next to something that stays pretty wet like sphagnum moss. This is a novice guess - maybe the moss is killing roots affecting the plants ability to get water to the leaves, so its starting to brown here and there. Are the new leaves browning at all and do you have other passis with sphagnum moss mixed in? I'd guess the plant would start aborting the old leaves (as it looks like it started doing with my ligularis from the excess heat). But I'm probably wrong, but good luck!
