My roses in pots are getting unhealthy with following symptoms
1. all new leaves are pale green and thin
2. old leaves are dying, mostly becoming brown from edges 1st
3. they grow 2 or more shoots from same spot (it looks strange and never happened before)
4. some leaves curl up
5. leaf with slightly yellowish spots
6. recently a lot of leaves fall from the roses
Would anyone please advise what could be the cause and remedy to the problem?
It is summer now and about 86~95F (30~35C) and 70~90RH.

|It is not unusual for new foliage to start out a different color than old foliage. That said, sometimes leaf yellowing is a sign of iron deficiency. And I think the conspicuously darker veins suggest this or manganese deficiency. I have the yellowing problem with The Poet's Wife and am planning to apply chelated iron.
I also have one rose that is planted in a seasonal stream that is yellowing, and I'm assuming it might be suffering from too much water, although I have thirty other roses in the same situation that do not show the problem. I have three more that I planted this year in a spot that turned out to be just a little shadier than I expected that also have lighter new foliage than I would have expected. All of these, BTW, are David Austin culivars from the DA farm in Tyler, TX. And I have had the same problem once or twice before. Not sure whether this has anything to do with it; but I've not seen it with any other roses. I'm thinking that getting adequate sunlight migh help my roses.
When dried up leaf tips happen to my indoor plants it is always from lack of water. But I've never seen a rose put out new foliage when it has too little water. I suppose that uneven watering might lead to it. Heavy watering followed by a drought just as the leaves are forming. But with humidity this high this seems hard to imagine unless the plant were in a pot that was definitely too small. I defer to others for better explanations.
