you guys are awesome. Does anyone have experience with Happy Frog Soil? I hear people rave about it.

I just got home from thanksgiving dinner and stopped by a friends to pick up his combo meter. Here is the PH readings I got from everything I use (stand alone):

tap water - 8.5-8.6
big bloom - 7.0
calmag - 5.2
tiger bloom - 3.1
grow big - 3.6
big bud (diluting a bit in a small amount of water) - 5.4

After putting all of this in a gallon of water (the amounts I put in are in the first post), I got a 6.1-6.2 ph level.

The soil run off from a plant a flushed well earlier today and pouring in a glass of water was at 4.4, which is quite distressing.

What's your thoughts? What really confuses me is this problem does not seem to get really bad until they are into flowering a few weeks. Before that I have the occasional bad looking leaf or two but nothing like this. Thanks.
