Compost teas are primarily a means of introducing beneficial bacteria and fungi to your rhizosphere. A simple tea of compost, dechlorinated water and molasses is the standard base. There are countless ways to tweak your tea in order to provide support for various actions in your plant. A simple base tea will not cause a toxicity nor will it swing your ph, especially with a soil amended with dolomite lime. If you follow your super soil recipe correctly then you have lime in your soil. I would never steer someone away from a tea when growing organically. I recommend a tea drench every third watering.Just don't over do it. I've added nothing but water to my grow for over 80 days.
Yes, my soil is amended, but I wouldn't add a tea or anything else unless I saw deficiency in my plants.
Plant toxicity and PH swings are never a good thing and should be avoided. Sometimes less is more.
