First, let me welcome you to the organics forum. It's nice to see another hydro gardener giving organics a shot. I believe that most of us started exactly as you are - hydro forever (or as long as you have been) before we got sick of paying for expensive bottled nutrients that only gave so so results. I personally did the hydro thing for almost 20 years before I ended up here.
First - your Compost tea. Compost tea is generally an aerated mix of water, earthworm castings or compost and a food source - molasses, fish hydrolysate, kelp, in minute amounts. This aerated compost tea is NOT used as a nutritional tea. It is used to ensure proper soil microbe levels in an organic garden - the beneficial bacterias that help break down organic matter and feed our plants. Soil microbes also help keep our plants healthy by battling off the bad microbes/bacterias. Luckily, "Microbeman" stepped in here - he is an expert in the field - listen to whatever he has to say; he's done his homework.
So, as this tea is not a nutritional tea, but is a microbe tea, use the 6 tbs that he recommends. What happens during the brewing process is that the original existing bacteria in the earthworm castings have found, thru the aeration process in the tea, ideal conditions to start breeding. They breed like crazy in the tea solution, overloading the tea with bacteria (and other microbes). When poured onto your soil, there is now millions or billions of these little critters in your organic mix, and they start breaking down the organics in your soil and literally feeding it to your plant. Your plant also secretes food to help feed these soil microbes thru its roots to keep these helpful critters close by, forming a "symbiotic relationship" with them - one hand washes the other. THIS is why you hear of folks adding molasses to thier tea - to feed the microbes. Remember, it doesn't take much.
I would try and source some kelp meal to top dress your soil with, and to also make teas with. I'm not referring to seaweed extract, but kelp meal - Ascophylum Nodosum. Kelp meal contains about every little micronutrient you need, but even more importantly it contains natural PGR's - plant growth regulators. These help keep internodal spacing short and tight - ie: less stretching.
There's a lot for us all to learn - you've come to a good place to get started.
Thanks for the welcome and information! I knew compost teas were to increase microbial levels but I thought they also doubled as nutrition to feed the plants. I suppose I should premix and top dress for nutrition and use teas for microbes. As you can see, I still have the hydro way of thinking: using liquids as fertilizers lol.
If I've got it straight from what you said, the microbes we brew in compost teas help "enhance" the food in your soil by breaking them down and feeding it to the roots. Without any food in the soil in the first place, the compost tea will have nothing to form the symbiotic relationship with. The microbes help "supercharge" your soil by increasing nutrient uptake and fighting off disease.
I'll definitely use your advised amount of EWC and pick up some kelp meal. Since the clones are still yellowing, I'm thinking about top dressing a minute amount of Chickity doo-doo fertilizer in conjunction with the ACT. This fertilizer is OMRI certified organic and has worked wonders on an experiment plant I keep outside.
