You don't need to run out and buy a wetting agent, but when you mix your foliar, you should add a drop or two of something like dawn dish soap. It will act as a wetting agent.
If you haven't read it already, I highly recommend reading my "Top 5 Lessons" link in my signature.
One of the things I want to emphasize is that you really don't need a lot of expensive nutes to grow a great, healthy plant. And, when they have problems, throwing more/different nutes at it, isn't always the answer, and to much extent can complicate things for a new grower.
This is why I suggested earlier sticking to the basic trio to help get the plants stabilized and your grow "dialed in". Once it's dialed in, all those other "additives" simply help you get the most out of a plant that would have otherwise been perfectly healthy without them.
In other words, the nutes don't make the grower; the grower makes the nutes!
