Switching Nutrients

I'm contemplating switching nutes from the Fox Farms trio to all purpose Dyna Grow. If anyone has any experience using Dyna Grow I'd really like to hear about it. In addition can I switch nutes in the middle of my grow.I'm 5 weeks into flowering. Thanks in advance.

I wouldn't switch in the middle of a grow, especially if I was smack in the middle of flower, like you are.

At 45 bucks a gallon, its all i use....
