If I added Canna boost on the 6th week (or 2weeks into flowering) is that okay?

I am using an nft system, im growing a haze plant, I have very little experience, but I am doing good so far, there are some nice big buds.. I am using for vegetation and flowering Canna product. After reading about canna boost recently , I added it on the 6th week or 2 weeks into flowering, do u think thats okay, or it may affect the plant in a negative way?

Should be fine m8 it states on their web site add as soon as you flick over the light cycle, the boost just allows it soak up more nutes so it will be fine
