Thanks guys. Ive had a lot of yellow leaves since week3 of flower im now at 6 week but my ph as been 6.0 so thats wrong.
Whats best thing to do now, would it be good to flush them 4 a few days with water at 6.5 with no nutrients or just half the doseage
of nutrients. This as probably been my problem.

for a quick temporary fix water with some calmag regularly. Be sure next time to add some lime to your soil mix.

Nitrogen deficient. More likely from a general lack of Nitrogen in your flowering feeding schedule rather than pH. Nitrogen is available over a very broad pH range in soil where other nutrients are not. If your pH was far enough off to lock out Nitrogen then your plants most certainly would be showing many issues. I would up their N a bit. A bit of extra Magnesium couldnt hurt either.

What strain is it? (if you know) - if it's an indica dominant then don't worry too much about the yellowing. If it a sativa dominant then maybe try and deal with it. Before I start to offer advice, I need to ask what soil you're growing in? If it's a quality organic mix then my advice will be pertinent, if it's something like Miracle Grow or cheap compost the advice might not be so accurate.
It might actually be more hassle to the plant trying to sort this issue now, than leaving it to cope with the yellowing issue - I would base my decision on whether to treat or not on the percentage of Indica/Sativa. If I was to suggest anything it would be to flush with ph 7 (neutral ph) water, put a fair bit through it, triple the capacity of the pot. Now, the important bit - check the ph of your run off. This should give you a clue if the problem you have seen was caused by a nutrient lock out due to low ph. If the run off is low (6 or below), then yeah, the 6ph water you have been given her probably contributed to the problem. If it comes out at 6.5 or above then I would say you were not really responsible. If you do find ultra low ph in the run off, then flush again with ph 8 water (do it in stages and keep checking the run off until it hits the magic 6.5). Once the run off is around 6.5 then introduce some nutrient solution, not too much, but enough to get her started again. Then don't give them any more water until they have dried out.
Or you could just leave them to finish, making sure everything you give them from now on is 6.5ph, and make the change from the start in your next grow. I have yellowing issues on the big hazey lady in the grow in my sig at week 6 - in that case due to her having some nitrogen sensitivity - doesn't really worry me though. She'll still finish fine.
Hope that helps offer some food for thought.

Yeah, that aint a massive problem - but she does look sativa dominant, so I would try and deal with it. Almost looks like a little bit of over-watering signs to her too (those necrotic, rusty patches).
I have to agree here. keep feeding LIGHTLY with nutes and add some calmag to your feeding.
