did a little testing with the ph of the diff nutes...

my watter = 7.4
w/ grow big @ 1 tsp. per gal = 6.5
w/ Tiger Bloom @ 1 tsp. per gal = 6.0
w/ Tiger Bloom @ 2 tsp. per gal = 6.0- it was just a tiny bit darker and my "kit" goes from 6.0 to 5.5 so I would "guess" 5.8
w/ Tiger Bloom @ 3 tsp. per gal = 5.5

so I guess it's time to get some ph up or baking soda......

oh yea I tested my soil again last night and it was still holding at 6.8
