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!
