is it safe to switch nutrient brands during the grow?

I am on my first grow ever as a new medical marijuanna patient. My problem is this, I went to a hydroponic store and got a decent starter kit for my plants. I use B.C. Grow with some other nutrients currently from B.C. but i want to switch to a Fox Far product. One of my plants is in a organic soil mix called Moravia and the other plant, my baby Aurora seed was just sprouted in Fox Farm Ocean and Seas potting soil. I want to buy some fox farm products but would like to just put my bigger plant on them to as it would be easier on me as opposed to dealing with 3 different brands. Is it okay if a switch the nutrient brands during veg. growth?

Not a problem to switch

Not a problem at all. If you look at the content labels, they are all VERY VERY similar. Some companies may split it into different parts, and separate bottles and give them fancy new names every few months. However, plants like what plants like. Name brands don't feed the plant, its the food in the jug
