Pic didn’t load to show but was clickable and this is what your referring to…
I’ve done a lot of research on this but am by no means an expert but I now usually only brew teas for around 24 hours. I haven’t tried that recipe. My experience is that with what I use much longer than 48 hours and my teas tend to go bad and not smell right…earthy like smell is good and sour stinking like is bad…
I use teas around every 3-4 weeks during grow. Remember during flower you don’t want to do a foliar application to avoid potential bud rot and the like just water them top side and maybe even some in saucers to let it wick up from bottom too.
Here is a post I made last night that might help.
I would think that the recipe from Great Lakes Water only has been tested by them and if using their products would work but i don’t know.
Are you using their super soil as part of your grow? I ask because just using teas through to harvest may or may not get you there…I don’t know. If using their SS it should as I have looked at their stuff just never tried it. So if not you may need to use other nutrients to help finish them.
Forgot to answer the frequency of using teas question… not sure what they recommend with what your using…but I use Boogie Brew and they state can be used every week but I don’t.
Hope this helps.
