So can you use the flora nova grow and bloom on the FFOF?Be careful feeding in standard potting soil. Much of it already has timed released fertilizer and if you start adding more nutrients you can run into problems.
If you know nothing about nutrients then just stick with the basics. You don't need a dozen bottles of stuff. General Hydroponics MaxiGrow and MaxiBloom is an easy 2 part dry nutrient. Their liquid 2 part FloraNova Grow and FloraNova Bloom is another easy off the shelf nutrient. You can buy a dozen bottles or 2 to get the same results.
