Thinking of switching nutes, created a schedule what are your thoughts?

Hey guys before I go out and buy these nutes i wanted to get some opinions.
Using 10gal smart Pots 50% Coco w/perlite and 50% promix
Tap water. My reservoir is at 15 Gallons (sorry if they complicates things)

currently using the Heavy 16 Line. Great line just becoming too expensive

Thoughts of what can be added or removed would be awesome!

I don't grow hydro but I over heard a conversation at the hydro store the other day. The guy was saying he switched nutrients mid grow and must have had some kind of toxic reaction. Plants grow only with one or the other were doing fine but the ones he changed mid grow all died. Just passing along what I overheard...
