Phrag. schroderae -- brown lesions on leaf
Hi all,
I've been growing a Phrag. schroderae for about 14 months and generally things seem okay (no flowers yet). Despite searching the forums and online, I can't find anything specific to what I am seeing on my phrag -- brown lesions on the leaves. They are slightly depressed and limited in size, typically linear in appearance, parallel with the length of the leaf.
I don't believe this is sun damage as I have seen these lesions appear in new growths that have been kept in shade. For a while it was receiving tap water but for the past 6 months exclusively RO water, with fertilizer (MSU recipe at 1/4 strength once a month). I use s/h for this one and flush with RO water about every 3 days. The new growths that have appeared in this time also show the spots.
Given the plant has been actively growing and has maybe 3 new growths starting, I don't think it is in dire straits. That said, I'd like to understand if this is expected or normal, or something reflecting poor care or a contagion. Many thanks for your input:
