Mix everything together in your dry potting mix... not everything there is water soluble.
This isn't an exact science- but the amounts listed sound about right for a 3 gallon pot.
With a great potting mix like this, you shouldn't have to worry about additional fertilizer for quite some time. You can make blood meal tea for a quick nitrogen boost, or use fish emulsion if your plants start to look needy, i.e. yellowing on lower leaves.
You've just about provided everything your plant will ever need in this mix. |
