I grow in soil, righ now i am in 2 gal. pots. I have 6 plants that are about 25-26 days through veg. I have been using only growbig mixed with rested tap water. I started at 1tsp/gal after 1 week of veg have worked my way up to 2 tsp/gal. My plants look healthy and all, but today when i watered and tested runoff Ph almost all of my 6 plants tested at around a PH of 5.... Why is my Ph droping?? I was thinking possible salt build up, I heard that FoxFarm products tend to create alot of salt..

I thought of something. The runoff itself looked a little brown or orange i thought, Maybee that along with the color of the Ph testing solution showed a lower Ph that it actually was... does that sound possible or logical at all??
