mushroom compost/AK48

so i planted the 4 ak48s you see plus 1 in my mushroom compost soil mix its only been 3days but they seem to be loving it....my question is do i have to feed them as often as i have been or will the compost act as a mild fertilizer?if i plant some clones in straight mushroom compost will it work?
any info will help

?any one any one

mushroom compost is known as SPENT mushroom media. not alotta nutriton left in it. it also holds too much water. i use it, but mix with other ingredients.

cool thx man i mixed it with my natural soil which can sustain growth on its own its just a little heavy...i added mushroom compost-
peat moss-
humus-
dolomite lime-
soil
and they seem to be doing good i just hope the lime stabilizes the mix so i dont have ph problems

old add some type of drianage material like vermiculite, pumice. perlite.

ya i thought about it but i dont think it will be necessary since my natural soil has perlite in it plus it has a layer of rock at the bottom and i forgot to mention coco is in my mix also
