My orchid's leaves are now brown and reddish.Is it receiving too much direct sun or is it something else?
The leaves were green in the past, like the center of the leaves.It is in front of a window.It has been growing for a while now.
The newer leaves have turned green.There are new leaves.Fertilizing helped.There is a picture of how it looks now.
This looks like a deficiency.When was the last time you added something?Maybe magnesium deficiency.Did the discoloration start at the margins?It's a good idea to know what you've added to the soil of your orchid.Is it found on the lower leaves?Young growth at the top of the plant is the best way to survive when there is a shortage of a mineral/chemical.
Plants need to photosynthesize when it's really low or insufficient to actually promote the making of anthocyanin.The color was purple.The flowers will be thin.It is energy for plants.For the majority of life.The little chemical change makes energy when the ATP is broken down.Did you see the last part?That is what it is.A plant that doesn't have this P will slow down.
The temperature of the soil would cause this plant to not be able to take up the available phosphorous if you fertilized it.The roots can't use this chemical if the soil is cold.
