yeah... 2 nodes.... I wouldn't be feeding anything yet... I generally feed at around 4...
So what I would do.. Give it a good flush, then just give it say 10% strength if you feel it necessary.
but honestly... Just let the water and soil do its thing if you want!
After it gets a few more Nodes.. Go 25% then over a period of a week.. Take it up to 50% then just go from there..
If you would like any more advice or anything please feel free to PM me!
I love helping people out!
