I've read a lot of different opinions on pH and ppm/ec.. I'm currently pH'ing my IN water/nutrient solution to 6.5 and my ppm run off right now is around 500 (3rd week of veg). I'm seeing a slight yellowing on lower leaves and from what i've read/been told it's probably due to me using RO water and not adding cal/mag (which I just started doing).. I didn't start feeding until last watering so I think I waited a bit too on adding nutes.. My base medium is OF 40% FF light warrior 40% and 20% worm castings.. Any help or insight would be much appreciated
 
You don't need to pH your water or fertigation solution... Cal/Mag isn't necessary either. Dolomite lime is the solution to those three issues. You can also add molasses to you RO-ed water at a rate of 1 tbsp per gallon for minerals.
