The foliage is getting very thick on my auto and flowers are coming in strong. Should I start to defoliate? Plus some of the leaves are clawing and there are some yellow tips.

As necessary to maintain good airflow within the plant’s canopy.
Usually a pH or excess nitrogen problem, or both. What are you feeding and do you know your runoff pH and PPM?

Not sure. PH is 6.8. I just put down some fish bone meal and top dressed with a little earthworm casting.
Is this an organic grow? Are you feeding other products? Cannabis needs a balanced diet of nitrogen, potassium, phosphorous, and micronutrients like iron, copper, boron, zinc,…
Using a nutrient rich organic soil called Indicanja. I just today fed them with fish bone meal and top dressed with a tiny bit of earthworm castings. PH is around 6.8. I assume that I should get some PH down and water that in.
You do not water in.ph down. Use it to lower water before adding. 6.8 is workable. A little lower is better but you are not out of range.

Definitely defoliation time, bud sites need light to grow.
I would suggest you lollipop first, then defoilate and remove any bud sites from the lower canopy line all the way down when you do (consider them Suckers that will never mature).
To boot consider stem thickness, if its not as thick as a piece of pencil graphite then ide toss it.
Yeah. Not a good idea like @Storm mentions. pH is measured on a logarithmic scale and caution is needed. 7 is neutral. 6.0 is 10 times as acidic as 7.0 and 5.0 is 100 times as acidic as 7.0. Each integer is 10x the previous integer. What growers will do is a gradual reduction where they will water with 6.0 to reduce the 6.8 slowly to 6.5.
