Your question is very welcome. because this one is the first try with this method!
I reuse old mix [originaly made with 2/3 of light mix and 1/3 of coco soil].
I simply add my compost [2/3 used soil for 1/3 of compost].
I was tired and not confident with guano tea so:
When they enter in 12/12 light, I cover the top of the soil with
guanokalong powder[NPK 1-10-1] I have calculated
8 grams per liter of soil.
i.e: smart pot #3 can contain 11Liters of soil... 8 X 11 = 88grams
I then top the guano powder with a few lombricompost [not homemade] just to cover guano.
then I put some water to moist the top and activate the guano
with the usual guanokalong powder the npk is 2-15-2, then I would give 7 to 7.5grams per liter of soil.
When the girls have one month into flowering, I add
comfrey liquid manure diluted into rain water [1L of manure for 9L of water].
I have found a brand that do it right and fully organik.
once around 28 and 35 days of 12/12 and another time around 45 and 50 days.
I have not (yet) found my own K source so the comfrey manure is very handy even If I would like to add this into the soil and making it my super soil for the girls.
Last but not least, about compost, in my garden I have some borage, chelidoine, bindweed dandelions, they are feeding my compost with very good nutriments.
I have in mind to grow those adventitious specially for my cannabis growing, they would be the perfect feed source.
borage like comfrey is a tough source of K.
dandelions are rich with P [maybe a good alternative to the guano]
Going organik is rewarding all efforts I made to understand how life is going in the soil and how the plants are feeding from the soil life.
