Recently, I've been thinking about adding fulvic acid (can't hurt) to my daily micro dosing and just saw your comment on it. May I ask what your source is (customhydronutrients mentioned above?) and how you determine dosage amount / gallon?
Deanna, I got my Fulvic Acid from Kelp4less few years ago. Far as how much to add and how I came up with that? well far as I know there is no way to accurately figure out the correct dose unlike other chemicals which gives us a % of certain content which can be calculated easily. With Fulvic Acid its little bit tricky, the closest we could come to calculate It, is by calculating the Carbon content based on https://www.webqc.org/molecular-weight-of-C14H12O8.html
Honestly, I have only tested it in my tank for few months, while it could give good results, but at the same time it could also cause this algae that looks like cyano and usually form on the tip of the plants, the results from using Fulvic acid was similar to adding Urea, there is tons of organics in this acid and you could expect some good amount of organic Nitrogen coming from this Acid, I add about 0.15-0.25 gram of Fulvic acid in my recipe for testing purposes, Adding too much resulted in some algae.
I also played with Humic acid and it probably isnít best used when mixing with the solutions.
thanks for posting , i see majorly two versions one is B 0.004 and other is B 0.014, which one to dose when?
you can use any of the above recipe from the list according to your needs, I wouldnít go based on which recipe to use just based on the Boron. However, try to maintain Fe levels around 0.1-0.3 ranges weekly, you can split the doses in daily dose or dose 2-3x week or however you like, but I wouldnít dose 0.3 ppm Fe in single dose. also, the only time you need to add more if your water is rich in PH/KH or say liquid hard.
