Mine looked like that a month or so ago, right after a repot.

I thought it was nute burn. So I bought a soil test kit at the local gardening store.

All my nutes were a little higher then they were supposed to be. So I flushed it out and let it dry. Unfortunately I over flushed and so the soil was deficent a few days later. Thus I started nutes.

However I would say they are fine other then likely to many nutes (IMHO). To be sure get a test kit.

Don't start over though. They will survive once this one issue is resolved.:thumbsup:
