I'd recommend not letting things just "sit" this causes things to go anaerobic. I'd also not recommend brewing teas at home unless you have a microscope and can identify strains of bacteria, fungi, protozoa and nematodes. The trials I've ran with 4 different air pumps at different lph proved to be...well not so good. Low lph almost every tea was bacteria dominate and anaerobic especially over 24 hours brew time. The highest lph still proved to be somewhat "off" as 1 of the 4 was anaerobic. Keep in mind compost teas are not a means to feed your plant, N-P-K means almost nothing in a compost tea, and feeding once a week with teas isn't the idea behind teas. Compost and compost teas are a means to put life into soil, let your microbes digest and release all the nutrients they can. Nutrient cycling from your microbes is all your plant needs. N-P-K is an outdated method to me, because anyone growing knows those three are nor the only essentials. Think calcium, magnesium, iron, hell even arsenic lol. I'll brew a compost tea after every re plant(I'm no till) and that's the only time. My plants get foliar fed aloe and kelp, that's it. Molasses isn't a good addition to me either, unless your growing early succession plants such as kale or other leafy greens(because it only feeds bacteria and they will feed out every other organisms). Cannabis is barely in mycorrhizal succesion to me. Long story short I personally think you should only use compost teas, or teas when your soil isn't proper. My two cents anyways.
