So, like lots of people here, I got the free samples from General Organics and I will be using them this grow on plants in coco, and plants in FFOF soil, to kind of do a comparison. So far (week 2 or so), I have been feeding the coco plants every day for the last week, about 1/2 of what GO's feeding schedule says. The soil plants are only getting BioRoot, BioWeed, and CalMg, no BioThrive yet since the soil is so rich.
I have been feeding the coco plants every day, and they look good but are a very bright green compared to the soil plants, I'm guessing this is because they need more Nitrogen, and the cation exchange of coco? Anyways, I am going to up my feedings of the BioThrive Grow for the coco plants.
Ok, so now that I've rambled way away from where I was going...
Here's the deal, I've noticed on GO's feeding schedule, they say not to adjust PH after mixing. When I've mixed up my solutions, it seems like the more 'Grow' I add, the lower my ph sinks. At about 1/2 strengh with the other additives, in evaporated tapwater, it was at around 5.8.
Since I'm just feeding the coco plants with this solution right now, I figure I'm ok since they should be closer to a hydro pH. But what is going to happen when I feed my soil plants with this same solution, maybe even at a higher ppm which will likely be an even lower pH due to more 'Grow' in the mix?
I realize adding a pH down/up is probably going to kill any kind of beneficials in my mix so that is out. Just wondering what your experience has been with these nutrients either in soil or coco. I read Jmansweed's nute study and it was very helpful, I'm just looking for a bit more specific info on pH.
