"Fertilizer salts form soluble ions in soil water. Increased concentration of ions increases osmotic pressure and decreases water potential, making it harder for plants to take up water. This is why plants affected by “fertilizer burn” look about the same as if they had been stricken by drought. They can’t get the water, because there’s too much salt in it." I cut and pasted this into my notes years ago. I cant remember where I got it. (when roots become over saturated similar symptoms occur) a firm understanding of osmosis goes a long ways to growing healthy plants.
Plants need a certain amount of salts. Even organic composts and manure contain organic and inorganic salts and as the organic material breaks down the salt level increases. Synthetic fertilizers are much more concitrated than organic material in both salt and nutrition.
This is where issues with microbial life come in. Each microorgamisn is just that, a tiny organism, a living thing. Just like us and our plants their survival and proliferation is dependent upon genetics, environment and resources. These organism have a maximum metobolic rate and although capapable of regulating natuaral fluxuation of evironment need relatively stable living conditions. Synthetic nutrients, do to their consintrated nature can throw this off more easily. Also there is organic material breaking down in the soil so it may be hard to regulate or measure salinity of the soil in hybrid synthetic/organic feeding. Disrupting the balance that your microorganisms work to maintain can be detramental. Flushing can have a negative effect on microbial networks as well, which is needed more with urea based nutrients.
Vermicompost tea is great for veg and pre-flower because it provides an esealy accessable source of nitrogen and is high in good bacteria. They love sugar! Aslo its hard to over do it! Bacteria for Robust Root growth!
I have found Forest Humus compost based tea is a better flowering option. Although they take longer to compost and brew they have a greater fungal content do to relatively high humic acid content. Fungi 4 Flowers!
Lastly I would not recomend adding
Great White shark to a tea till after its brewed. Bacteria spread and reproduce a whole lot faster than fungus. The bacteria will out-compete and even eat your fungi. Plus unlike the bacteria fungi need something to attach to.
Oops, one more thing, watch out for high trichoderma
inoculants. Trichaderma is the cheapest and most aggressive of the fungi in these things. The trichoderma will take over and leave little room for microbial diversity.
Not trying to solicit but this product is the Bees knees and at $50 a lbs a great deal! They also offer a 4 oz package.
