If you use organic additive just make sure you run bennies so your protected against disease. If you add organic in your rootzone and you have just a start of slime or any root disease, it will explode in few day and ruin your crop.That why I'm very carefull with organic additive because when you add them to rootzone, you usually create the perfect environment for bacteria and fungus to thrive , but it might be the bad one who take place.
I'll add , theres very few benefit from using floralicious plus but lot of cons.
Hope it help. gl
