This brug..."Tommy xxxx?" grew beautifully and then the leaves started looking like below...I fertilized, put down the Witches Brew (epsom salts, calcium etc.). No signs of mites or thrips.....
Diagnosis?
AND, the new growth is stunted, with ruffly leaves and it looks all "bunchy"....
bumping this so it doesnt get burried..
I want to say maybe broadmites, but really I dont know what Im talking about LOL.. I just remember seeing something about stunted crinkled new growth and broad mites. And those are SO hard to get rid of.
Wish I could be more help.
Without seeing it in person, I would agree with Shelly. Crisp/thick new growth and a slight bronzing of the leaves indicate broad mites also.
Carol, chlorosis is caused by a lack of iron or magnesium. When the clorosis starts from the bottom leaves on upwards, its lack of magnesium, when it begin at the top, its lack of iron. Both a too low or a too high ph-value of the soil can cause a malnutrition of the two minors even though, you feed with a good fertilizer.
The stunted growth of the top could be caused also by malnutrition but also from broad mites. A better picture of the top would be helpful.
THANK you all. I have a brand new really cool Meter (pH, moisture, light and fertilizer from Charlies Greenhouse Supply) which I will take out tomorrow. and test. Will also spy for Broad Mites....saw no webs...but broads often aren't obvious.
Monika...didn't know about the top to bottom clorosis thingy....will always remember that. Thank you so much!!!!
You guys are great!
Thanks,
Carol
PS ....and from what I am told the Broad Mites love to live in the new growth nibbling away and causing havoc. OK, that makes sense with what is happening to the leaves. Tomorrow I will whack the whole think back and burn the cuts. That'll show 'em!!!!

I did not know about the top to bottom or bottom to top clorosis either and depending where it starts from determines what is lacking in the soil. . . very interesting.
I will save this because I will probably need to refer to it one day. Monika is a book of information and I find this very helpful to know.
Here's a stupid question......what's the difference between magnesium and manganese?
Also, would this same thing apply to oleanders? My oleanders always seem to get yellow leaves at the bottom of the plants then drop. I've seen other people with the same problem.

A web search found this.....
Web definitions for Magnesium
A light, silvery-white, moderately hard, malleable, ductile, metallic element which only occurs in nature as a compound with other elements, as found in magnesite, spinel and olivine. In ribbon or powder form magnesium burns with a brilliant white flame, (the so-called magnesium light), which is used in signaling, pyrotechnics, incendiary bombs, or in photography where a strong actinic illuminant is required.

Web definitions for Manganese
A gray-white or silvery brittle, metallic, element which resembles iron but is not magnetic. It is found abundantly in the ores pyrolusite, manganite, and rhodochrosite and in nodules on the ocean floor. Manganese is alloyed with iron to form ferromanganese, which is used to increase strength, hardness, and wear resistance of steel.

Brugie,
How does this all relate to which is best for plants or which is used for what symptoms on plants? Thanks.
Beats the heck out of me. I just looked up definitions. I do know that I take magnesium and my fertilizers have it in them too. The other one...I have no idea what it is or what it is used for.
Check this out. http://en.wikipedia.org/wiki/Manganese Doesn't sound like anything I want to eat.

Mangan is one of the important minors in plant nutrition.
This came as part of an email I got today, and I thought of this thread.
BONE PROBLEMS? EAT PINEAPPLE!!!
Bone fractures and osteoporosis can be prevented by the manganese in pineapple.
