Sounds like you need more co2. A .8 PH drop at the end of the photo period isnt enough for high light. What is the drop when the lights come on?

Id shoot for a full 1 point drop by lights on, or pretty soon after, 1.2 a couple hours later. Adjust it slowly and watch the livestock so you dont kill anything
Ok, I'll check it today.
