Just get any basic nutrient. You don't need any designer brand that has you using a dozen bottles. Nutrients are important but as long as you provide the nutrients the plants need they don't care if it comes in a bunch of shiny bottles with cool sounding names or a plain bag of Jacks 5-12-26. The ingredients are all sourced from the same suppliers and from the same fertilizer plants located around the world.
Yaramila, megacrop 2 part, dakine 420 3 part, Athena core and bloom only, front row ag grow and bloom.
I know that you know this but I'm posting for others that think this line or that line of nutrients is somehow special.
Most people don't realize that a good portion of the bottled cannabis specific nutrients are all made from the same ingredients manufactured by Yara, Mosaic, CF Industries, and other large fertilizer companies at the same factories. Just like with LED lights, the brand on the fixture might be different but the internal parts all made at the same factories in China. Nutrients are the same way.
Advanced, Megacrop, Fox Farms, General Hydroponics, etc... None of those companies make the raw ingredients. They just buy them in bulk and mix them together. The raw ingredients are all made at chemical factories like this one in India.
