Hydroponic Fertilizers – For Leafy Greens, Herbs and Lettuces
This Video is from the Youtube channel: “Hort Americas”.
This is part 3 in the 3 part educational video series on hydroponic fertilizers from Hort Americas. This video focuses on how to build and adjust a hydroponic fertilizer formula based on the quality of your source water. Fertilizer formulas mentioned in this video are specific to leafy greens, culinary herbs and lettuces.

I saw that you took 17% off the mg/L for P and you briefly mention this is due to impurities – How is this figure calculated/defined? is it arbitrary?
Do you have a lab recommendation for source water testing?
hydroponic fertilizer npk 20 20 20 solution formula ratio tomato
1 mg per liter its equal to 1ppm , according to the table the sum of all the ppm for “hort americas 9-7-37 hydroponic base” is 238,21 ppm, when you have added 544 mg/liter of the fertilizer…
is it posible that level of nutrient impurity?? or what is the reason for this difference?? is it the tpa? what other occult nutrients there are?
This spreadsheet doesn’t work when downloaded. It’s just a PDF that you can look at and not use at all. What’s up with that?
Guys, you are awesome! Thanks a lot. This really helped a great deal!
You recommended an RO system in the video. My experience has been that RO systems tend to remove a lot of the minerals from the water.
What are your thoughts on the use of rain water or distilled water in a hydro system. I’m still in the building stages and I’m starting out, so I’d greatly appreciate your thoughts.
RO is only recommended if there are excesses of something in your water. A water analysis is so important so you are not adding what you don’t need. If you add too much of something, the additive can become toxic to what you are growing. Every water source is different, hence the need for a water analysis. This can also save a lot of money in nutrients that may not be needed.
Rain water would be ideal if in a rainy environment. Distilled water can get very expensive.
