Recently went to promix as advised by Pute, and am having issue about 6ish weeks of flower. Looks like PH problem, going in around 5.8, runoff 6.

What am I missing?

One thing, I did not know I should have put a couple inches of perlite in the bottom, maybe a root issue? A couple of the plants are 2 weeks ahead of others and will be chopped soon, can then do a post mortem on the roots.

A root bound plant could be part of the problem.

What size containers?

those plants that are near to harvest , will you be cutting back the feedings or just gomwith plain water until harvest?
 
I have the same issues with no problems. Been that way for years. I adjust by lowering your ph to 5.5 when you drench. Many will say ph at runoff doesn't matter.
Whoops. I went up to 6 last night, some of my mix was at 5.3. Ill try lower next watering.

Buds seem unaffected growthwise ..

Thanks,

Bubba
