I'm not familiar with the Tiger bloom etc so cannot answer your questions there.

As far as carbs go...my hydro guy seems to think that about 10ml/gal of Sweet is about all the carbs that a plant can generally handle. The res of your carbs, sugar, carboload etc is wasted.

I love Liquid Karma and highly recommend it

Sounds to me likey you want to go a little too crazy with all the nutes. I'd cool it....more isn't always better.
