Soil Question

Yeah, that should be a good ratio to start at.. though it depends a bit on the source of N. Is it 100% available once dissolved? If it is a source of Nitrogen that requires microbes to break it down before it can enter the plant, you want closer to 2-1-2 ratio. This is a gneralization that invovled rounding errors, so something like 5-6-10 can be thought of as 1-1-2 to give an example of how to use this suggestion. Calcium nitrate, for example, is 100% available the moment it is dissolved and does not require any additional molecular modification from microbes. Ammonium nitrate is also immediately available, i believe.. i see it in my nutes that are 100% chelated / 100% dissolvable / 100% plant ready. Looks like you are soil, so that opens possibility of needing more N. The problem is while soilless/hydro nutes precludes the possibility of having a non-100% ready source, "soil" nutes do not 100% preclude 100% readily available N. Need to know the source. of N. Read ingredients.. Google them to find out if plant-avaialble immediately and 100%. Also, use more perlite/vermiculite or similar.. you want about 1:1 ratio with that sort of substrate. Looks heavy. If more akin to water capacity of coco, only 2substrate:1perlite ratio is needed. you want what amounts toa 50% mixture of air and water per volume in the pot. higher water capacity soil needs more perlite to achieve that.
