what should a Promix Soiless medium ph level be at during bloom cycle?

I am using Promix soiless medium and have had a ph of 6.5 for veg. now that i am bloom i see a lil yellowing. is my ph too high?
5 weeks old
1 week in bloom
in 3 gallon pots
bontanicare bloom organics
1000 hps
80 degrees

No, I'd say give them some veg nutes. A little more N.

yeah , maybe i backed off the veg nutes a lil too early or sumthin. will go 50veg/50bloom nex time.peace.

I don't even start on bloom nutes till a few weeks in.

will go back to 100% veg and see what i get,preciate it.

No problem bro.
