They don't go all the way through (yet), but they seem to be getting s l o w l y worse. I can't say that I much care either since everything is producing well and it doesn't seem to be affecting them.
I'm not puzzled really, i'm fairly certain it's the Bushmaster that's responsible. Whether it's presence in the soil caused the soil chemistry to change (since I use organic soil), or the actual plant changed, I know it affected something, i'm just not positive what exactly.
There's not really a possibility of light burn/humidity, I never notice any condensate anywhere, and it's too uniform in it's appearance to be related. I would expect something like that to be sporadic, where this is very uniform. It has started at the leaf margins near the serration, and ever so slowly crept inward toward the veins. All instances are the same pattern, just varying in how much they were affected.
It's pretty much isolated to the larger, older fan leaves. I don't see any spotting at all on the leaflets near the buds, so like I said before, I'm not really too worried about it.
I just wanted to throw it out there so everyone could see it well, and keep a close eye when they use BM. I'm leaning toward a change of sorts in soil chemistry or in the microorganisms that reside in the soil. I'd be interested to see if anyone that's used BM in a hydro system had symptoms like this. My guess would be no, but it's just a guess. I only say that because it appeared gradually a week or so after application. I would think that a res change in hydro may keep this from ever showing up. Just speculation though.
