I am hip to the coupon code, I saw the OCG video and signed up for the newsletter. Worked out to be a pretty good deal, from now on I think I will just order direct from them. They have exactly what you need, and just stock up so the shipping is free.
I mixed up a micro batch the final numbers were PH 6.32 and PPM 152, sound good? Man that Zeus was hard to see in the syringe, and Olympus works like a champ. The few times I had to use GH Up to raise ph seemed like I had to use a decent amount to get it to move.
