I use Grow More - Sea Grow (All Purpose & Flower/Bloom). I use other powders and liquids to achieve NPK ratios for different stages of the grow. My "schedule" is here:

It's kind of like a multi-bottle "lineup." But, using ordinary off-the-shelf stuff. Sea Grow is my base. But, it could be Jacks Classic. (Lots of people use Jacks. You can mix Classic, the Fruit product and the Flower/Bloom product to get NPK ratios that are between each of those products.). I like Sea Grow because it has more organic-sources of nutrient. (MiracleGro "Tomato" works well too. I've used it all the way through one grow. It was fine.).
I don't think I'd change anything your current grow. It looks good. If you're trying to simplify a multi-bottle setup... Cannabis doesn't need much fiddling with nutrients. A 1-1-1 NPK ratio all the way through works fine. Lots of people do it. Often with Jacks Classic.
