I always plant straight into batmix & start using nutes a week after. in the seedling stage i use bioheaven & rootjuice.. week 2, heaven, & grow.. but then again biobizz nutes work different to normal organics.. they react with the soil rather then the plant. If you get the latest biobiz schedule from greensea or biobizz site.. follow the all mix schedule if using batmix & works a treat... only useful if you're using biobizz tho....
