I am growing basil in terracotta pots in a sunlounge. The seeds were sown in well-drained compost + vermiculite and the plants look (mainly) green and healthy. I have grown them successfully on many occasions. But this year, a number of the leaves have what I can only describe as transparent patches - it looks as though somebody has scraped away the green colouring on both sides of the leaves. Some leaves are brownish on the edges too. Can somebody tell me what this is - and what I should do?
