plagron batmix

Hi folks, was hoping one of you lot could help, iv'e just invested around £500 on gear for my next grow (4th), fans, filters, cooled hoods, nutes etc, i decided to go organic this time and bought plagron batmix, it didnt at the time but now i realise it's probably gonna fry any seedlings/clones, i was wondering if i could just dilute the batmix with wormcasts to get around this as i already have a sack, or should i grudgingly invest on a soil more suited toclones and seedlings.
Thanks.

For seedlings/clones a standard potting compost is best. When you repot then you can add wormcasts, bat shit, etc

EDIT:
Standard compost AND a little perlite with a sprinkle of wormshit would be ok

as i suspected, thanks for the reply
