I'm new and reading a lot so there might be a perfectly good explaination but from what I gather you're using a soil that apparently works from seed to harvest.
I don't understand how one soil can do it all.
If the plants at the start require more N which they do the medium needs to provide it, if you have too much PK you can induse early flowering in some cases but either way you would need a ratio higher in N at the start. If the soil is an all in one how can it contain the correct balance in N and PK through out the life of the plant?
For example during flowering you need more PK and during grow you need N. What brand is the soil I'd like to read into it a bit.
Another concern I have is nutrient consumption. As a plant grows it uses up different elements that aren't just PK or N but also cal, mag, zinc and other stuff (long list) but as it's growing those nutrients are being taken out of the soil unevenly and not replaced with anything else. It's there food for a good couple months and it seems like that soil is very very high in nutrients which would logically be very very bad for seedlings and plants in there early growth. Seedlings don't need anywhere the same amount as a fully grown plant but your medium apparently provideds both. I just don't understand that.
But from a person who has just finished reading up about nutrients and what's required during the different processes I don't understand how one soil can contain it all and be efficient and effective.
I guess you would have to constantly be changing the PH of the soil to force certain nutrients into the plant? But that seems more of a pain then anything else and something fairly hard to maintain over several plants in different pots.
Does anyone get what I mean or am I just being a noob?
Each to there own I guess but I'd recommend learning about soil management and how to put in the right nutrients then going with an all in one soil that from what you say seems to be producing undiserable results.
