Lyfespan, not putting lime in the soil is a mistake. You are still going to "have control" over your pH as chemical based nutes are always pH'd. This is for the soil, not for the nutrients. I am strongly advising that you add lime to your soil mix. I am confused though, using that soil and GH nutes, I do not understand the addition of bat guano, green sand, bone meal and myco? As soon as you hit the microbes with the chemical nutes they are gone--why even add them in the first place? If you kilo the microbes, these substances will never be turned to food for the plant. There is no such thing as being "close to" organic--you either are or you aren't. LOL--kinda like being "sorta Greg".
I do do things a bit different don't I THG, here's my thinking here, I love the soil to do its thing for as long as it can, but we all know that's not long, these girls eat more than any of us is realizing. So I let them devour everything in the soil, when I see the lil yellowing in the new growth, I start the feeding. Girls probably get 2 GH feedings per stage of life(before transplanting)so I'm using half the nutes now too. As far as the lime goes, I will re check my meter and see where my run off is, I have never had any issues with lockout, so I have never worried about the lime. Btw my watering is always with 5.0-5.5
Gaiant, I just like growing organic for bud I am growing strictly for meds. And like you I just wanted to know more and there is a whole lot to know. I always have GO nutes on hand as I have never been able to make my super soil go the full distance. These are the organic nutes put out by GH. Also Espoma makes some great products that you can often buy at regular gardening stores and big box stores. I am particularly partial to Bio-Tone and Plant-tone. But I use a lot of their other products, too--perlite, meals, lime, etc. Remember that organic means 100% organic, with everything being organic.
