Phalaenopsis leaf tip problems

[Arizona Jeanie]

Hello Gene, and welcome to the Orchid Board! Stick around, there's lots of good information here, plus a lot of opinion and advice from experienced growers.
You have accidentally posted your question in a thread started by "Phal grower" with his own question. Not wanting to hijack his line of questions and answers, you need to start your own thread with your question. Here's some information on how to do that:

Go to the "Beginner Discussion" area, click on the "Forum Tools" tab along the top, and choose "Post a New Thread". (Or just use the blue "New Thread" button on the upper left.) Go ahead and enter your question, post it, and start your own thread, and all will be right with the world! You may get back some questions to answer about your own growing conditions and circumstances, that information really helps with getting you the right advice.
Congratulations on retirement, getting interested in orchids, and figuring out how to join into the discussions here!
And Phal grower, apologies for barging in but I thought a bit of re-direction was in order for Gene.
