Is this a good liquid bloom to use.

I would suggest you dilute your stuff about 50%, not a requirement, just less likely to overdo it

Absolutely. Start low and slowly work your way up to as much as she can handle. If you start to notice signs of stress from nutes, you have found your nute level. Just back it off a little at that point. It's much better than having to recover from nutrient burn or lockout or death.

I use 50% strength Tiger Bloom, and a few drops of other stuff like Liquid Karma.

PPM meters are cheap now. That's the best way to tell if you are over or under doing it.
