absolutely, no other fertilizer, but the composition of the tea changes throughout their growth, depending on if you want to make them grow and only bloom a little, or slow vertical growth and make them explode with flowers.
Each plant is different so i make two seperate teas and blend them based on what i feel the plant needs most at that time for it to live up to it's potential.
I also take any over ripe fruit i have and save it for the teas, i've found organic pineapple, pears, and apples make great sugars instead of molasses, or boosted by a little of it, so they don't only have one type of carbohydrate and can make use of different types of sugars; make sure to smoosh them good or dice them so they have maximum surface area. if you use mycorrhizae they will love the additional organic matter to break down. the acid content of the fruit also seems to help the uptake of the nutrients for plants and it needs less additives for an acidic pH. Keep the kelp and fish emulsion constant throughout their growing, it doesn't hurt them one bit. I use different bat guanos with either high nitrogen or high phosphorus, then a third with higher potassium, and mist them with an epsom salt solution for magnesium. my teas are always comprised of kelp, fish emulsion, and bat guano.
I use them once a week, sometimes every two weeks, but that depends on your concentration and how much fertilizer you want to make available to your plants(and how much they can consume based on your soil and watering habits) if you miss a month they'll slow down a little and may drop a few flowers or pods but they won't die or anything drastic.
