I'm going to use soil. Probably MG or FF. also, Is 23-3-3 good for flowering?
23-3-3 is not good for flowering.
Nitrogen: promotes green growth. The first number on the bag is the percentage of the bag that is nitrogen. To promote beautiful green growth a higher nitrogen number is the important factor in making a choice of fertilizer.
Phosphorus: promotes flowering / blooming and fruit formation. The center number on the bag is the percentage of the bag that is phosphorus. It also promotes good root and seed development Remember seed formation follows fruit/bud formation which follows flowering. For more buds choose a fertilizer with a higher P potassium number. Fertilizers for tomato plants, african violet plants, and other specific fruit/flowering plants often have a higher P or phosphorus number.
Potassium: promotes growth of roots and stems and helps the plant breathe in carbon dioxide and release oxygen. The last number on the bag is the percentage of the bag that is potassium. A higher K or potassium number promotes overall health and root growth......for flower you would want the second number higher, then the third, then the first...example 2-8-4 would be for flower
