Sugar peak grand finale flush??

Please can anyone give me some advice as product really doesent if i am supposed to flush this or if i can go straight to crop from using this? If i flush it how long for before cropping as i am worried i am using it but plant is looking like need cropping very shortly?

ive used it and i like to flush for a week or so, bud seems to taste and burn better to me if i do.

Cheers as it seems there is little advice on this product as on bottle and on net it doesnt seem to say if to flush or not. Even though its organic prodcut i generally still like to flush my plants prior to cutting but woundered if this completly destoryed the idea of this product.
