Hello! I am a relatively new gardener and I have a question about my \"Siam Queen\" Thai basil plant. When I bought it the leaves were green. About a week or so after planting, a lot of leaves on the plant developed a partial reddish/purplish or plum colored hue. Where I live we have had a lot of rain and maybe a disproportionate amount of sun. I fertilized my garden with aged sheep manure when I planted it almost three weeks ago and I just gave the plants their first side dressings this week with an organic fertilizer (I forget what the three number nutrient designation of the fertilizer is but it\'s they are all low single digits) I was wondering if anyone could tell me why the leaves are discolored? Thanks! Any help would be much appreciated! Ps. The pictures are taken today and the plant seems to have less discoloration today.
