Girls Early In Flower, Want To Buy Flower Fuel, Do I Need Cal/mag?

[SmithsJunk]

My girls are in early flower, 3 Sativa @3 weeks, 3 Kush @1 week, recently fed 7-3-1 organic bat guano mixed in topsoil. Because of flower they got a little nitrogen toxic. Flooded them, they perked right back up. I'd like to nute for flowers with Flower Fuel 1-34-32. Do I need cal/mag? Would cal/mag be enough? Or just bone meal since it has magnesium sulfate. The bat crap is still there at 7-3-1. Is there anything else I need? Not spending over $25 total.

I wanted to try AN Big Bud and Bud Candy but I don't know what's in them, so I don't know what I'd need or if they'd cause more toxicity.

If my questions are dumb, sorry, I'm still learning.

I finally found a bottle of AN Big Bud with the NPK. So I went with Advanced Nutrition.
