Pale leaves on my Phals
Hi,
I'm new to your group and would like to say hello. I hope someone could help me. My phals have been developing very pale leaves. Just one or two leaves per effected plant. Sometimes the leaf falls off when I touch it. Is this common? Is there anything I can do, or should do? Thanks in advance for any help. Eric Adam |

Could it be natural aging? How many leaves do the plants have? How do you grow? Window, lights, gh? How do you water? How often? What do the roots look like? How is the media that they are planted in? Do you fertilize? When and how much? Have you looked under the leaves? Any signs of bugs? Have you sprayed for bugs? With what?

Was this yellowing at the top or bottom leaves? Was the leaf completely
shrivelled and yellow when it fell? When you say the roots look healthy, are you just talking about the surface ones? Tip out the plant and check the entire root system. Also, hold the dropped leaf, and the leaves on the plant to a bright light so you can see and check through the leaf. Does everything look normal, i.e. even colour?

The've been fertilized and I treat them with neem oil. They all have spikes and are almost ready to flower. The yellowing happend so fast and it was the entire leaf. I was wondering if the plant was drawing energy from the leaves for the flowers because I 'm not using enough fertilizer. |

Florida --- I'm jealous. Cold Kansas here. How bout light, you say
shaded, how much shaded? I've seen leaves on plants turn yellow from the mealies, but they take over the whole plant, like white cotton, so I really don't think that's what's going on......Keep this group posted....Burr |

Thanks for all the help everyone. Garland, thats exactly whats
happening. Yes, it had been a cool a few weeks ago but I thought they were in the clear. It sounds like cool weather may be the issue. Mine started to yellow at the bottom too. Did the leaves on your phals turn completely yellow? Eric |

Oh, Yes! They turned yellow, then brown, then crispy, then fell off. On
one of my nicer plants (of course...), I'm currently left with one pristine leaf and one half-green leaf. The rest are toast. I'm sure the plant has been set back for a year or two. We'll see what happens. At least this particular plant has an extensive root system and I'm hoping that this kind of underground horsepower will help new leaves appear and grow quickly. We'll see...
