Hi Iva Thompson Welcome to Plantix Community and greetings to Croatia. It might be due to increase in Anthocyanin content in plant. In order to retard this content you need to increase Chlorophyll. Following are few measures 1. Use Seaweed Extract or growth regulators like Tricontanol. 2. Magnesium and Sulphur have rapid mobility and also catalyze Chlorophyll production. Provide Mg or S at regular intervals. Thanks
