ph hydro problems - What am I doing wrong?

I'm growing in both a DWC and soiless (50% each coir and peat moss)I ph'd my water to 5.8 but after I adding my Fox farm nutes (3 tsp of Grow Big), my ph dropped to 5.3.

I always assummed you ph'd first and then added nutes. Should I again readjust my ph one more time to reach the optimum 5.8 point?

yes... readjust. You should only adjust your pH after you add the feed.

DUH!!! Guess I was Back Asswards huh?

Thanks
