hey there, the organic tea you're making is actually pretty damn strong already, thing is as it's not synthetic you wont "see it" explode in your soil. It'll take a few days if not a week to start really juicing up in there, and the risk is by adding more you risk over doing it. I would say stick to the instructions, but if you've already done it with less, do it again with just that bit less you know... for teas it's better to go with the full dose, but only once because they contain bacteria spores that have some sort of critical mass required to get the desired effects, and dont forget to water them at lights off when you do add the tstuff : the light fries the microbes you brewed ! hope this helps ! 🚀
