Problem with Phrag QF Angel Wings

[richard.feldman48]

I have a Phrag QF Angel Wings with lots of healthy leaves but browning on some of them. I've looked at the St. Augustine site to try to identify the problem, but I find it difficult. I've attached two photos. The one of the leaf tip looks to me most like anthracnose. The other looks a little like one of their pictures of erwinia. But for all I know, it's something else entirely. Advice appreciated. Thanks.

Test the TDS /PPM of the root zone substrate for high salt content.

My assumption here is that the potting mix was allowed to dry out, but there could be other causes. Do you grow this plant sitting in water at all times? Did the saucer dry out at some point? Is that a new growth that's starting to climb out of the pot but which hasn't yet produced any viable roots? Is the existing root system in good shape?

Doesn't look like Erwinia to me, so I think you're okay there. Erwinia has a very distinctive smell, sweet fermenting, rotten scent. So, if you want to rule that out, give the rot a sniff.

The 78 photo of leaf tip die back could be poor water quality, feeding too often/heavily, unhealthy root system, and/or the media was allowed to dry too much. The damage in the 77 photo is what happens when a Phrag is not receiving enough water, was allowed to dry out too much / too long, and/or the roots are in poor condition.
