P.Brandywine bumpy soft ,green curling leaves
Firstly, I'm a raw newbie. Please forgive any faux pas. I have 3 plants of different varieties, heirlooms, and Hybrids. All 3 plants are in large pots. Pots are closely adjacent, up against a wall in the only sunny spot I have,others still OK. Everybody was doing fine until the top, new leaves on Pink Brandywine started curling up. Still growing fast, still bright spinach green, but getting more weird bumpy curling each day. After a week, the curl started migrating down the stalk, affecting lower, healthy, previously well-established leaves. I wondered if it was a deficiecy, bug, disease, or what. Mutant plant, still going strong. I took several pics. But it took me so long to succesfully get an account here, the whole plant is now affected. Any guesses? I have a guess, but don't want to affect the consensus.
