MG Nute release burning my seedlings

Realizing now that MG with time released nutes arent so good for ur seedlings and young plants. Is there any way i can bring down th ph of the soil or dilute the nutes given off by the soil. All comments and adivce is much appreciated.

flush with water. and no, MG time release is bad. when you water, the nutrients are released, more water = more nutrients. so you need to water the crap outa them. also, its easier to deal with abundancies/deficiencies, when your soil/fertilizer isnt full of all of them.
the reg 20-20-20 MG stuff aint bad in smaller doses but time release is usually bad news

Thansk nick i think im gonna try and transplant them into smaller cups with outside soil until their older
