How big of a pump are you using and for what size batch?
Your tea seems pretty good but you don't need the humic or the kelp. Lots of times when I am having trouble thinking straight with EJ I refer back to the hydro-organic FAQ and the labeling of the bottle to see what ingredients are in them.
12. I mixed a solution using the Earth Juice Original Formulas "Advanced Chart" and my pH is 3.90? Since 1991 the mass majority, including ourselves, of gardeners who use the Earth Juice Original formulas simply mix with water and use without adjusting the pH. The initial pH of Earth Juice Original formulas will generally be on the mild acidic side, this is primarily due to the natural phyto-acids and amino-acids contained in many of the Earth Juice formulas. These are considered "Weak" acids that will help transport (chelate) nutrients for easy and rapid use by the soil microbes and plants. Earth Juice will adjust and be conditioned by medium and beneficial microbes supported by the applications of Earth Juice.
If you prefer to adjust the pH prior to using here's a few options:
Always mix with portable TAP water and use a high quality professional planting mix.
A. Aerate the solution for 12-24 hours. After the aeration period if the solution exhibits an increased in the pH, do not adjust and use as is. If there is no increase in the pH, adjust the desired pH and use. For the next mix, prior to the aeration process, adjust the pH to 4.5 followed by aerating for 12-24 hours. After this period if there is not increase in pH adjust to pH and use
B. See the Earth Juice "Advanced Plus" Chart. The initial pH using the "Advanced Plus" Chart will generally be a bit higher.
C. Try a partial substitution of Earth Juice Big Bloomin Guano for proportions of the Earth Juice Bloom. Example: 1 tsp/gl Earth Juice Bloom + 3 tsp/gal Big Bloomin Guano. Use Big Bloomin Guano during the Vegetative period at 1-3 tsp/gal.
D. To keep it as easy without any worries, use Amazon Bloom as your medium and follow the Amazon Bloom "Keep It Simple" Chart.
I know it's not a direct answer to your question but I feed 10 + strains the same exact Earth Juice based schedule without ph'ing or bubbling, and have always had fantastic results. Using Grow and bloom will cover your Cal-mag needs , but you are only using the bloom it looks like.
What exactly do they mean in that answer by phyto-acids? Well that's their fancy way of saying humic/ fulvic is already built in so you won't need to add those into your mix because it's already chelating everything. Fulvic/ humics do not effect the pH of your soil negatively and you can feed with them freely without worries, as their FAQ states. So definitely cut those out.
The 3LB recommend a 24 hour bubble time to bring up the pH a little, but I have heard many others say the same thing, that the pH will soar above 7 the longer you go (especially much longer than 24 hours) .
AS FOR CATALYST: I personally love catalyst and hate going without it... it's something that I use every watering pretty much. It's like an all in one for your plants and works with or without the extra fertilizer.
The malt, yeast, molasses and oat bran do a good job of feeding your microbes whether you brew a tea or you are just feeding straight to your soil, and on top of that provide enzymes *hence the name catalyst. You can pretty much stop spending the extra coin on hygrozyme to see the overnight results.
here's another clip from their faq on catalyst:
20. Can I or should I use Earth Juice Catalyst with other plant nutrients? Yes. Catalyst (Canada Xatalyst) is the number #1hydroponic additive in the world. It will improve the performance and effectiveness of all soil and hydroponic nutrients. Due to the potential of accelerated nutrient availability, use caution when using Earth Juice Catalyst with granular synthetic timed released fertilizers.
