I haven't tried that exact combination, but I did well with PromixHP and one of the 3 part liquid nutes. You definitely need to keep the nute levels under control, salt buildup late in the grow is a pain, and is the reason I have given up on autovalves and salts. If you are not going to put anything between the pots to limit the water quantity needing to be absorbed during each flood cycle, I suggest a straight perlite layer an inch or so deep in the bottom of your pots to increase aeration in the flood zone. With all the extra water, the flood zone will stay flooded for longer, especially early on when plants are smaller, and that could lead to root issues due to oxygen starvation. OTOH, straight perlite might not wick enough, so you may need to include a small portion of Promix to help with that.
Good luck with it.
