Here's another picture.

Your plant appears healthy. Maybe post a pic of the whole plant?

I can't tell what is causing this but I wouldn't worry. Did you check for mites or bugs under the affected leaves?

Jane

tanie, I would like to see a close up of the entire plant without showing the blooms. Get as close as you can but include all of the plant.

#1. In your firs post of the entire plant with blooms, its hard to tell, but to me, the plant appears not to be getting enough light, and also appears to be a bit droopy, like its not getting water. First check there would be for root rot. If the roots are ok, then it could be a combination of lack of light and waer.

#2. Now, the possible bug problem. Get a magnifying glass and look under the leaves where the spots are. You are looking for tiny little bugs crawling around those areas, or perhaps tiny patches of what look like spider webs covering parts of the leaf under those light spots. Tell us what you find.

Bill

Hi Bill, here are few more pictures close up. I couldn't see any crawling things under the leaves. In fact, under the leaves are all nice and green and no blemish of any sign. But on the top with blotchy and look like when you got burn and blistered the worries me. Thank you for any helpful tip. It is a beautiful plant with a lot of flowers still on after 4 months.

Tanie. (I will have to post 1 at a time, still don't know how to multi post yet.)

Ok, tanie, the last photo may be the one we are looking for. Does the plant we are talking about live on the plant stand on the left in the picture, or does it live on the plant sand by the window behind the plant on the table?

To me it appears that it is not getting quite enough light. The long dark green lush leaves are what I base that statement on.

The window in the back of the photo looks more like the light intensity the plant needs, but the bright spot of full sun over the other plants is worrysome. Have you perhaps recently moved the plant from someplace else to that window? If so, your spots may be small sunburn spots. If that is the case, I would put a very light curtain or thin cloth over the window, especially when the sun is coming directly through it and shining on the plants.

Answer these questions and we will go from there.

Bill

Hi Bill,

This is exactly where it stood. I put it there since I have it 4 months ago but I moved it to another spot yesterday because I thought it might be sun burned. It is facing east, sun shines in about 3 hrs. from 7:30 to 11 or 12 o'clock but it's kind of dapple light because I have trees in the backyard. It doesn't get artificial light from right or left of the sunroom which I have them on for 14 hrs. for cool climate orchids but sunroom has 3 skylights. It's might not get direct sun light but the room is very bright.. The glass is low-e glass and it's supposed to shield the uv out. The windows do have 10 % sheer shade but I thought it's not sheer enough so I don't put it down. If you look at the picture of the other additional post to show it to Jane, you'll what the shade is like. You can see through the sheer at day time but I thought it's a bit too thick still so I don't pull it down.I just took this picture right now and today is quite cloudy and rain outside. You won't see well from this picture. I didn't check the roots because I afraid will disturb the flowers. I don''t think it has rot roots though (just guessing) because it's potted in coconut husk and it seems to drain very well. Should I lift the plant out of the pot to check even with flowers on?

Thank you!

Tanie

Tanie, I wouldn't worry about it. Looks like a beautiful, healthy plant. Could be some minor nutritional issue or maybe some sun spots. I don't think its anything I would be concerned about unless it spreads.

Your plant appears to have been blooming for quite a while. If it were my plant, I would cut off the spikes (yikes!) and let the plant grow over summer and regain some energy. It will make some new spikes and bloom in Winter. Otherwise, don't look too closely!

Good growing,

Jane

Oh Jane,

Cut the spikes off would be very hard for me to do!! One of them still have bud on. I will have to "disobey" you this time unless that is the only thing I have to do to save the plant. So sorry!!! I will keep watching it closely to see if the spots will spread.

Thank you Jane and have a great weekend.

Tanie

You can leave the spikes!! Don't get upset, I like my plants to grow over the summer without the added stress of making flowers. But, it is not necessary. You can let it flower for years.

Don't worry about the plant, I think it is fine.

Jane

Tanie, Ok, its looking more and more like it might just be sunburn. You need to keep watching it to make sure It does not turn into something else, but if it is sunburn, here Is what you should expect to see. As long as the plant does not receive additional burn, the spots should not grow any larger. You can expect the worst of the spots to become sunken to some extent, and the very worst of them may eventually become thin, leathery, and dark (almost black) Unsightly, but as long as they don't get larger than they are now, they should cause no real harm to the plant.

Now, lets see if we can prevent this from happening again. Phalaenopsis are not high light demanding plants when compared to Vandas and Cymbidiums, for instance. They do need their light though.

The location where you are growing Phal's, whether inside or outside, should be very bright on days when the sun is shining and there are few or no clouds. On these bright days, if you place your hand between the plant and the sun, you should see no shadow, or at most a very indistinct shadow of your hand on the plant. If you see a very sharp, distinct shadow on the plant, it probably is getting too much sunlight.

Over time the leaves on your Phalaenopsis plants should be a kind of medium yellow green. if the leaves are dark green and lush looking you probably need to increase the light.....do that slowly and carefully, if you push them out into more light too quickly they will burn.

Hope this make sense and helps.

Bill

Thank you Jane and Bill for your responses and advice.

Jane! I am kind of a keeper. When I go fishing, if I caught a fish I want to keep and eat it. It would be hard for me to put it back in the water!! So is orchids. It would be hard for me to cut flowers off. But I am willing to do what it takes to make the orchid plants healthy and bloom!

Bill, I will try to test the sun light the way you showed me and will keep a close eye on the plant

Thank to you both and have a great weekend!
