Q.Brown Spots On New Leaves Of Azalea
I live in S. Carolina by the coast. 3 azalea plants were planted, approx 3 ft apart. I was told this azalea blooms 3 times a year. Currently there are abundant flowers & buds. One plant is full with stems, leaves, flowers. The next is not quite as full but growing upward with many flowers & buds. The third is small & has not grown very much but currently has blooms and 13 buds. However, the new leaves have brown spots and the older leaves are drying up on the ends. All three plants get full sun in the morning. It has been an extremely hot spring & summer. Have been every other day due to weather. What do you think is wrong with the smallest plant? Thank you Sorry it’s 11pm and I don’t have pictures.

Unfortunately, without photos it will not be possible to determine the cause of the issue.
I can take a few guesses, though.
These can be symptoms of too much water, too much sun, or infection. Too much water will lead to infection, most of the time, so these can be related issues.
Morning sun should not be an issue, but if the one that is not doing well get more sun than the others, then this is likely the issue.
If that is not the case, then there is a chance that the plant is receiving a little more water, or is in a lower spot than the other two.
Depending on what the issue is, you will either need a fungicide, or a shade cloth to protect the exposed shrub. Make sure that the soil only dries out to about an inch, but don't let it stay wet. This causes infection.
