help not sure on the problem!

PH is like 8ish I just don't know what else to do ive searched for hours days n no results I was thinking light bleach from going from a 8bulb t5 to hps but this never happened with my wing reflectors y would it do it with air cooled and perfect temps don't make sense lol

i think ur plants good like sand said the new growth is always a little off in color my tops are aliitle more yellow then normal but when they get older they get greener, i would keep an eye on it but since u flushed u should be ok, never ran promix but had a buddy who was haveing problems with ph had to keep it down around 5.4 i guess the strain he had like it low

Week 4 n the buds look like this!?

That's a berry bomb at 4 weeks n the Acapulco gold
