It looks chlorotic to me. That can be nitrogen and iron deficiency. It can also be caused by over watering. Nitrogen flushes though the soil with water. Too much water can reduce the amount of available nitrogen, as well as reduce the amount of oxygen in the soil. Iron is better absorbed with nitrogen, like taking Vitamin D with Calcium. One aids the other to be absorbed and utilized. It shouldn't surprise you some look that way while others don't. If they were all budded to the same root stock, so all the roots were genetically identical, they would pretty much be afflicted with the same maladies at the same time, within the limits of the scions' genetics. But, they aren't. Each one has a different root system with different capabilities. Some absorb iron more easily than others, just like some people absorb nutrients from foods more easily than others. That's a huge benefit of having a garden all budded on the same root stock. It's often easier to figure out what to feed and how to to use. With each root system often completely different from the next, it can lead to one area requiring more of some type of fertilizer than others. Check to see if the pots seem water logged. If the soil appears, feels and smells as it should, then holding too much water shouldn't be the issue. What have they been fed, how much, and when? Perhaps these particular plants require heavier levels of iron and nitrogen. Multiflora types do here in my garden due to their inability to deal with higher alkalinity. Many roses aren't as efficient in dealing with lower nitrogen and iron locked up in insoluble compounds due to alkalinity. Sometimes, the plants grow much more quickly than they are able to take up the nitrogen and iron. I used to see that in the old garden when heavy mulches of fresh horse manure were applied then heavily watered in. A lot of nitrogen from the urine pushed the growth faster than iron could be absorbed, or when insufficient iron was available because the conditions were still too alkaline so it wasn't being released. If the issue is seen in older leaves, it means it occurred when those were growing as new foliage, or perhaps the plant is preparing to shed them as they have reached the end of their useful life. In new foliage, the issue is currently occurring and can be "fixed". If you have recently fed them, perhaps they are being pushed from the freshly applied nitrogen combined with the heat. If the food didn't contain enough iron, they may benefit from something which contains a bit higher available iron. If they haven't been fed in a while, they may be telling you they need feeding. It's also possible there is enough iron there, but they are reacting to the iron being locked up in the soil by alkalinity. Perhaps the ones already showing the issue are more sensitive to it than the others, or those pots have become more stressed than the others due to being more exposed to reflected heat or direct sun? It's difficult to determine without actually seeing how they are arranged, how they are exposed to potentially affecting causes. Might the affected pots get more heat from nearby hard scape? Or, might they not get as much sunlight as the ones not showing the chlorosis? If the others are heading toward the same condition, it sounds as if it's heat, water levels or lack of fertilizer. The ones already showing the symptoms are either more sensitive to the issue, or are encouraged to be more sensitive because of more heat to their pots, pushing them to grow more vigorously, using up the available nutrient levels faster. When and what did you feed last? They are showing they seem to need more iron and nitrogen, whether it's because they didn't receive enough; it's been flushed through the soil by more water; are being pushed by greater heat; are reacting to alkalinity issues; or are just in a more vigorous growth spurt than those nutrient levels can efficiently provide for is difficult to say from the photos. What seems the most plausible to you? Thanks. Kim

I know lots of people disagree, but I really see no point to "babying" plants unless they have just sprouted from seed. I think they get a better start just putting them in the ground...that's where nature puts them. You are even in a pretty warm zone so they should do very well in the ground. Actually, I don't think I've ever had a plant not succeed by just plopping it right in the ground...and taking care of it, of course.

Thank you Ann! I looked up pictures on google of hoya's and found one that only said Carnosa....but, I wasn't sure if it was correct or not.....but, the leaves were identical. This wasa cutting I got in a trade about 3-4 weeks ago....and, it rooted like a champ and is taking off! :O) Thanks again for the help!! Frances

I know a few really fun games. 1)Guess that baby food. Use a disposible plate that you can write on. Section it off in however many flavors you want to use and number each section, one plate is prepared for each guest. Put spoonful of babyfood on each section and have your guests try and name that flavor. You can have guests write it down on paper/with corresponing number. ie: 1)bananna, 2)pear... and then have someone announce the flavors to see how many people guessed right. Its really funny! 2)You can do this casually during party. Pass around a ball of string/cord. Just cotton/or kite string or whatever you have that works. Have each guest cut off a length that they think will fit around moms belly. Whoever gets the closest wins. You do have to have mom stand there while each person sees if their string comes the closest to the correct circumference. You do need a good sense of humor for this one!
