simple little trick i've used and seems to work ok, if your soil mix is nute rich and maybe a little hot i place a tube in center of pot ( cardboard , pvc, whatever) and poor hot soil around it. then put peat and perlite or seedling soil inside tube to make a core of "safe soil" for seedling to be planted in and grow down its taproot. as it get bigger it will root out into hotter soil. just don't leave tube in thereits just to make the core
This is what I would have done (or cup tier system) if I had stuck with
