Orchid leaf problem

11 years ago

I have several Phal orchids, I am fairly new to growing orchids and recently have started growing under lights. Several of my leaves are developing yellow blotches on the top of the leaves. Could someone help me with a diagnosis and maybe a cure? I am hoping this in not a virus but just not sure.

Hi, a few years ago when I just got started with orchids I had ago similar problem , now I with as only using natural light though.apparently it easy ago fungus that with as as spreading a got the time and after talking to some fellow orchid growers it learnt they had the same problem.it with as as as in our rainy season.anyways I learnt about Phyton 27 and it has proven to be very effective.now I was also thinking about the light but think light damage would not be so spotted.do you use any kind of spray regime with your plants?

Did you mist them in direct sunlight? Water droplets can magnify the light and cause burns if it's hot enough.

I have seen that when a sucking bug like scale was on the exact other side. Show a picture of the bottom side of the leaf.
