I have leaf damage on my sweet potato vine, Ipomoea ‘Ace of Spades.’ It came that way when I bought it. Looks puckered. Then, the small leaf veins dry out around the puckered/embossed areas. The leaf cracks at those sites. Looks like it’s disintegrating. No apparent insect chew holes or leaf miners found. No insects found. I inspect every single leaf and quarantine new plants 30 days. No other issues on this plant. I propagated several small pieces. New growth looks fine on both the cuttings and at the mother plant. Any ideas? Background: I’m in Zone 9. Got it two weeks ago from the grocery store (delivery). I thought it was heat stress from the 100°+F temperatures here in the South causing the cracked dry leaf veins. But, no dry leaf tips, yellowing or wilting were seen. No bugs. So, I did not return it to the store. The soil was very dry when it arrived and retains water about 5 days before completely drying out. I use a moisture meter. I typically water every 2 -3 days in this heat. It’s kept outside on a covered patio. It gets morning light until noon. Gets bright indirect light after noon. I have not fertilized it the 2 weeks I had it.
