found this in another thread:
something close to 2-1-3 ratio (i.e. 6-3-9 or 12-6-18 ) for veg
and a 1-2-3 ratio (for example 3-6-9 or even 6-12-18 ) for flowering when adding nutes to soil.
also found some sticks my mom useing for some of here plants
not that bad for veg 14-7-8 tho K could have been a bit higher ..
but I guess thats just proof that you can find many diffrent once .. so I guess it just looking for sumthing close ..
guess its better to use some then nothing at all if you cant get the right once
and they also only cost like 5$ or so for 30 pices .. enough for like 6 plants doing Veg as it takes like 6 weeks to break down ..
just have to find sumthing els for flowering then .. and I would only add 1 at the time .. maybe evry week after the fist 2 ..could work Im sure if you realy dont have any other way
atlest you safe some money on expensiv nutriens and all the hazzel of give it to em and not over do it aso.
