Unfortunately organic companies are forced to go through OMRI or be questioned if the product is truly organic. Good racket but OMRI will put their mark on anyone who is willing to pay for it with very limited testing. I don't trust OMRI and if you research them you won't either. **Q: Does this product contain any edta? what do they use to chelate the nutrance?** A: 1) does NOT contain any EDTA - EDTA is a chemical synthetic chelating agent (probably the cheapest and therefore most popular, but we don't use the synthetics) 2) Elements are more easily absorbed by plant roots in a "chelated" form. Organic or All Natural Chelates are organic molecules that can help retain and release ions of many important nutrients, including Calcium, Magnesium, Cobalt, Copper, Zinc, Iron, Manganese, etc... 3) A Chelate is a molecular compound where cations combine with organic compounds forming a ring like structure. Amino Acids are one example of an organic compound / chelating agent that is found in the GS Plant Foods Liquid Fish Plus Kelp. This chelation allows the plants to take up / take in these nutrients and increases the mobility, usability and availability of the nutrients for the plants. **Q: How many gallons of solution will the gallon of concentrate make? What is the recommended fertilization regimen suggested for this product?** A: The bottle I have has the following instructions:Foliar spray: mix 1 tbsp per gallon waterHouse plants: 1 tbsp per gallon every 2-3 weeksOutdoor plants: 1/8 cup per gallon every 2-3 weeksLawns: 1 gallon mixed with sufficient water to cover 8000sqft monthly **Q: can I used this for hydroponic growing?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Liquid gold for your garden *by on Reviewed in the United States May 26, 2026* ⭐️⭐️⭐️⭐️⭐️ Liquid Gold for Your Garden—Without the Awful Stench!If you are on the fence about switching to an organic fish and kelp fertilizer because you're worried your backyard will smell like a rotting pier, buy this bottle right now .I’ve used cheap fish emulsions before, and those definitely require a clothespin on your nose. But GS Plant Foods uses a cold-processed blend that is totally different. It just has a mild, earthy, marine scent when you mix it, and the smell completely disappears within a few hours of watering. My neighbors haven't complained once.Here is my honest breakdown after using it for a full growing season:The Pros: The 7-Day Turnaround: I had a couple of stunted, yellowing pepper plants that were struggling. One week after a root drench with this stuff, they pushed out dark, glossy green leaves and a ton of new blossoms. Zero Burn: You cannot mess this up. Unlike synthetic chemical fertilizers that will scorch your roots if you mix them too strong, this organic formula is incredibly forgiving. Built-in Weather Shield: The added kelp is the secret weapon here. My tomatoes usually wilt and drop flowers during our brutal July heatwaves, but this year they held strong and kept producing.The Cons / Things to Know: Even though the smell is mild to humans, neighborhood cats and dogs can still sniff it out. Pro tip: water it deeply into the dirt so pets don't try to dig up your fresh soil. The Cap: The bottle arrives sealed, but be careful pouring it. It’s a thick concentrate, so use a dedicated measuring spoon or cup to avoid spills.Final Verdict: This is hands-down the best all-in-one organic fertilizer I’ve used. My veggies are bigger, my flowers are thicker, and it's completely safe for the environment. A single gallon lasts forever because you only need 1 to 2 ounces per gallon of water. Worth every penny! ### ⭐⭐⭐⭐⭐ This GS fish & kelp plant food is phenomenal *by on Reviewed in the United States April 2, 2026* This fish & kelp liquid plant 🌵 food has far exceeded my hopes. No plant ☘️ food that I have ever used has caused such a rapid & clearly visible growth increase. The magnitude of the profound growth increase which this causes has been stunning.Seriously. Today I am ordering my 4th gallon. The amplified growth when using the fish/kelp formula over the past years on my cherry tomato plants & indoor plants has stunned everyone who sees my plants in person.I start with plants available locally. Due to the immense size & yield that I am growing these cherry tomato plants to, 🌵 I get the same variety every year. And I get the most robust looking & the largest plants I can find.With this fish & kelp formula, my cherrytomato plants grow to 12+ feet. The first year of testing this combination formula -- I grew one plant to 14' 7" . Yes, I did. That is 14 feet, 7 inches of high-yielding, really enjoyable fruit production.Organic plant growth.In 2025, three plants yielded thousands of cherry tomatoes. THOUSANDS ! And at the end of the growing season I was forced to harvest all remaining tomatoes before the frost lands where my plants live.I pick & later rinse/dry each cluster of green tomatoes -- which are then sent to retire & ripen inside of brown bags -- when they decide to ripen.. The reason to relate all of this -- is this: At that last harvest in 2025, between just 3 plants, I still (then) picked 380+ green tomatoes !!People are shocked at seeing these tomato plants. They are SO tall & loaded with tomato-clusters that I have to anchor the stalks to 7 foot tall garden guide-rod spikes to which I add a 3 foot extension.I also have to use a stepladder to tend these plants. Thanks have to go out to the producers of this astounding ORGANIC plant food, GS Plant Foods. So... Thanks for this stuff !!"High Performance --- Naturally!"written on my last bottle.I don't think that i could be more emphatic in my recommending this.My reorder is going to be placed momentarily.Review written 4.2.2026 ### ⭐⭐⭐⭐⭐ Product honest review *by on Reviewed in the United States July 29, 2026* Best product I have used.
