Hi everyone

High. :thumbsup:

Anything you have added to the soil lime and peat moss

Why? The lime I can understand, as Fafards is pretty acidic. Most peat-based potting mixes are going to be acidic unless buffered. But why the additional peat moss? It's ph is something like 4.5ish.

Lighting source and distance from plant 150w HPS & 2 CFL, 18"

Too far away. 12-16 inches is where I keep my 400w HPS, depending on maturity. CFL's don't work much past 6 inches or so.

Do not add anything else that will make the soil more acidic. You'll stunt or kill the plants.

Soil probes are crap, so don't put much stock in their accuracy. A ph pen is your best bet.
