Review: You need nothing else fertilizer - I have been using Maga Crop part 1 for a few years. With Mega Crop part 1 you don't need anything else. It is a full spectrum, single part fertilizer containing NPK, calcium, magnesium, sulfur, and all essential micronutrients in chelated form. It replaces multi‑bottle systems and eliminates the need for PK boosters, bloom bottles, or routine Cal‑Mag. It is the only nutrient I have needed for my tomatoes and peppers from seedling to harvest, except when rarely I have an issues requiring some Cal-Mag. . I would not use the dosage recommendations printed on the bag, they are more for cannabis which is far too much for garden vegetables .I stay in the 3-5 gram (1-1 1/4 tsp) per gallon range depending on stage of growth. I fertilize more often for my grow bags and less often for garden soil. For grow bags I fertilize every other watering to keep the salts from building up. Review: Works amazing, and the price is great - Very easy to use, with my RO water the ph has stayed between 5.89 and 6.28 at all strengths from 1\8 to the full 6 grams in flower. This is my first grow since getting my script and it has been amazing. Harvest first plant in two days. I did what most people say not to and started multiple strains and only have an issue with one plant having a calmag problem which I blame on the pheno as I have two of the same ww and no other plant has shown the same problem. This appears to work amazingly as a stand alone with the majority of plants but I would recommend extra calmag on hand, a little extra silica never hurts either. This is by far cheaper than any premixed nutes and you can try a sample off their site first and just pay shipping (which is what I did.). The sample is plenty for a smaller run, I have 5 in flower and four more in veg and have about 3/4 of the sample left still...I can only imagine how long this 20 plus lb will last. Only thing I don't like is the nitrogen balls draw in moisture and start sticking together. I have it in an air tight container with silica packs and it still happens so I would recommend pulling out a smaller amount from the large bag and sealing the rest in a food grade bucket with silica packs, only open to refill smaller container and leave sealed the rest of the time. Hopefully that will avoid so much moisture. I read they are changing up their recipe so perhaps moisture and calmag will not be an issue anymore, who knows. Either way it is affordable, easy to use, and works amazing. If your new to growing research everything first (I spent 4 months scouring the net before ever making a purchase.)from strains, breeders, electrical requirements, nutrients, deficiencies, temperatures, lighting, fans, ducting, water ph, Rh, lst, hst, monster cropping, mainlining, reverse osmosis systems etc and you can avoid the majority of newb problems I have read about. I have a lot to learn still but didn't lose any plants and have a MUCH larger yield than I expected for a first run. ## Features - Pro's choice for growing Tomatoes, Buds, Fruits, Vegetables, Flowers and more! 25lb size makes about 2500 Gallons of solution - 1-Part Complete Premium NPK Formula with Organics combines at least 7 products and supplements into one! - Maximum Plant Growth Weight and Harvest Quality Potential with minimum effort! - Multiple Forms Calcium and Magnesium, Sulfur, Trace Elements and Amino Acid chelates for Max absorption uptake. - Soluble Silica (Potassium Silicate source), Ascophyllum Nodosum Seaweed Kelp Extract, Fulvic Acid, Enzymes, 18 L-Amino Acids, B-Vitamins and Oligosaccharides ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B097WP61TK | | Best Sellers Rank | #43,336 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1,216 in Garden Fertilizers | | Brand Name | Greenleaf Nutrients | | Coverage | Full | | Customer Reviews | 4.7 4.7 out of 5 stars (1,125) | | Item Form | Granules | | Item Weight | 400 Grams | | Manufacturer | Greenleaf Nutrients | | Mixing Ratio | 1lb:100 gallons | | Model Number | 742776993062 | | Specific Uses For Product | Hydroponic | | Target Species | Tomatoes, Fruits, Vegetables, Flowers | | UPC | 742776993062 | | Unit Count | 400 Ounce | ## Product Details - **Brand:** Greenleaf Nutrients - **Item Form:** Granules - **Item Weight:** 400 Grams - **Manufacturer:** Greenleaf Nutrients - **Specific Uses For Product:** Hydroponic ## Images ![Mega Crop 1-Part Complete Base Nutrient - Hydroponic and Soil Fertilizer for Plants with Organics – Easy to Use for Max harvests - Image 1](https://m.media-amazon.com/images/I/611FvBQwXyL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ You need nothing else fertilizer *by J***C on March 4, 2026* I have been using Maga Crop part 1 for a few years.
