I +1 all the above posts.
I'll add in that I prefer brewing my greens "grand pa" style! I throw some in a glass tumbler, fill with 70-80 degree water, and constantly top up as I go along! Works best with Long Jing I think
The fun in tea is the experimentation! I know it can be frustrating when a tea is horrible and you can't seem to fix it, but honestly, it's more rewarding to experiment yourself and find a solution that suits your tastes best!
You said you lowed the tea:water ratio by a gram, well other teas may require it lowered even more, a change in water temperature etc...
If you have some free time and small gaiwan (60-90mL) then you can have some fun fine tuning the brewing parameters for your green teas without wasting too much
I'm not suggesting it's bad to ask about this by the way! I always asks these sorts of questions, but I've learned over the last year that, taking the suggestions as a vague guideline and then experimenting until I find the perfect parameters is always the most helpful
Hope your tea tastes nice, and remember, always trust your instincts and palette, if you feel you need to deviate from the guidelines, do so!
