Plant Magic Plus Supreme Soil, Do I need to add nutes?

Hi guys I am using a rather expensive type of soil for my grow its called "Plant Magic Supreme Soil Plus"



Here is the ebay link: http://www.ebay.co.uk/itm/PLANT-MAGIC-PLUS-SUPREME-SOIL-WITH-ORGANIC-GROWTH-STIMULANT-/271471452145?pt=UK_Baby_Baby_Feeding_Bottle_Warmers_Coolers_LE&hash=item3f34f59ff1

Should I go ahead and add nutes to this or is it already jammed packed with all the nutes they could possibly need throughout the whole cycle?

I have foxfarm grow big and tiger bloom but am not sure whether to add it to watering or not

Please help and thanks in advance

You'll probably need your nutes. See if they list ingredients on the back of the bag.

Unfortunately, I through the bag away, if anyone has any ideas of the content that would be great, I don't wanna burn my babies if the soil is already packed full of nutrients

I would just call or email the company direct with your question since their website doesn't say either.

I've sent them an email will have to wait and see what they come back with..
