My original education was that you had to have at least a two part mix because some elements are not stable when mixed and stored together. I see a lot of nutrients now seem to have the one component systems. While the two part system is a little more complicated the first time you mix it up, it really is simple once you have the gist-of-it. Also the requirements of a seedling are different than that of the plant when it gets closer to blooming and fruiting.
Also; I hate shipping water! So using dry ingredients and mixing myself really appeals to me.
In the photos you will see I used the lettuce nutrients to get the early (first) stage growth going. Now I am going to put them on their respective mixes for each plant. Look at photos to see more details on the plantings.
I will try to do an update as the plants grow.
Hope this helped.
What I found works quite well is to have two small half gallon size containers, I used bleach containers. I mixed 67g of a well mixed part A into one container of water, and 61.75g of a well mixed part B into the other. (I found these values by weighing each solid nutrient and dividing by the recommended amount). When it comes time to mix a nutrient solution up, I shake the nutrient containers a bit, and pour one cup of each solution into a 5 gallon sized container.
I fill the container until it measures in the correct EC range, which I typically get to around 1.95 mmhos/cm, after that I adjust the pH of the solution to around 6. Although its quite rare, if the mixed nutrient solution is not used up within 2 weeks, I dump it and start fresh.
Having a pH and EC meters are mandatory. Having the wrong amount of nutrients / the wrong pH will kill your plants. As a side note, 1 cup of each solution typically gets a 5 gallon bucket about half full for me, if you need more at once, add more nutrients and add water until the EC registers correctly.
I built a large outdoor system for spring. My test pilot of 16 lettuces under led + 400 w mh is doing the job. Will post photos at 21 days. Photo 1 is one week 16 hrs light day in utility room. Based on mpgardner setup. The 3 liter is a school project.
Here is a photo at 4 weeks. We ate one head at dinner. Good flavor.
