Greens, Methi, Coriander - Soil Mix | Container gardening | Commercial Hydroponics farming

For plants like coriander, greens, methi and spinach we cannot be transplanting and if I understand correctly they will continue in the large pots or plastic tubs right from germination to harvest. Can I know what is the ideal mix for these? I am using 50% coco Peat and 50% organic compost (the shop owner said there are some additives added to the compost). For other transplantable plants, I believe it is best to leave in seedling trays for 4-6 weeks and keep applying liquid nutrients in the form of tea compost or water mixed with compost.
