Hey Stinky,
Thanks for your help. I am only following the fox farm feeding schedule...week 7 & 8 require Grow Big (6-4-4) in addition to the Tiger Bloom and Big Bloom. Is it possible that the Ph levels are that low because of the recent nitrogen boost? I flushed a good amount of water through yesterday as I was checking Ph levels...I will test again next week to see if the Ph balanced back out.
I will for sure check out the soil flushing post...

Thanks again for your help!

SeaLevelGrower Reviewed by SeaLevelGrower on . Ph level of run-off.... Hey guys, I was checking Ph levels of run-off today and had a few variations. What r your thoughts? To high, to low, okay, perfect? What do I need to do to adjust if necessary? All of my girls are in FF soil with a heavy mixture of perlite added, and I am following the FF feeding schedule using all FF nutes. I occasionally add SeaPlex about once a week, and use Molasses on non-nute days. All plants are under a 400w HPS. ( I am using a digital Ph pen to get readings) Big Bud: 30 Rating: 5
