MG soil and seeds

hey all.
just recently i came across 3 seeds i germed them yesterday and today they are all popped,just waiting for the taproot to come out.
but i have a question about my soil for starting. it miricle grow and it has fertilizer...but its only .5-.7-.5.i just want to know if this soil will be ok for my seeds. its the only soil i have and the dirt outside is horrible quility.
will .5-.7-.5 NPK burn a little seedling or should i just not worrie?
thanks peace

I've heard MG soil is not good for seedlings.

i have also heard that its not good but since its the only soil i have and i dont have money to get better soil. i have to use it cuz i just germed some seeds the nutes in it are just a decimal amount.
should i fush the soil with water to wash some of it away?

Can you cut the soil with anything? Maybe run out in the back yard and get some nice dirt from the garden? Again, I have no experience with it, but I've heard it will burn the plants at a young age.

i replaced a little chunk of the soil like 3 inches down and about 2 inches wide with soil from my other grow. i also flushed the soil a little bit

Add some more perlite and you should be fine.Alot of people use mg soil or soil you can get from home depots gardening center.
