Ok, I flushed with 6.5 ph water and saw that the runoff ph was low, around 4 or 5. Flushed a few more times with water around 7.5, and along with a light dose of all fox farm trio, also with a high ph. After using this, runoff was still low, so I flushed again. Its still less than 6.5 but I think I'll leave it for now so I dont rinse out the ferts that just went in. I have 2 120mm pc fans running 24/7, 1 in, 1 out. The plant is about 18" tall in 6" pots. I've been using nutes all along, but probably too much. I am re-using old maricle grow, is the fox farm nutes enough to make up for this? Thank you so much, let me know if you need more details. +rep if you help me fix it.
