Yellow/Purple leaves in week 6 of Flower

Heyo! Need some help!

4x Sour Grape Kush
2x 300 led
FF Ocean forest in 3 gal
78 degree day / 70 degree night
50% humid constant
FF Big Bloom during weeks 3-5

So... I had a major ph issue whereby my tester's calibration was apparently off since day 1, and up until a week ago was watering with a ph of 7-7.2. Not ideal, I know, but glad to have figured out that part of the problem. There were a few signs earlier on but I though they were related to a fungus gnat issue I dealt with during mid-veg. And now the ph problems are also looking like n and p deficiencies (lockout?)

New growth had always looked ok so I thought I'd be fine. Not anymore. The tiny leaves coming out of the buds are now also turning yellow and purple and are showing yellow tips.

The yellow tips I assumed were from nute burn when I was using the Big Bloom mid-flower (1 tsp per gallon every other watering) so I stopped the additional nutes completely.

And now here I am. Last few weeks before harvest and am concerned my girls aren't going to make it. Don't think it makes sense to start adding nutes this close to finish.

Any help or insight would be greatly appreciated.

Your plants look great. Lots of them turn people on their own.

Thanks Sunshine- I wish this was just the naturally occurring slight yellowing/purpling near harvest . . . but between the fungus gnats, ph problem, nute burn/lockout and feared root rot (I need to check this tonight), I believe these symptoms are problematic and not normal.

They don't look terrible just faded early ... I'd givem plain ph water for a few more wks n chop...maybe a late boost to see if I can get one last swell in bud but water only till they finish.. how do the buds smell??? Remember Ya not smoking leaves.. your at the point where u ain't gonna correct the leaf issue n TBH they will only get worse from here on out.. just watch the buds which look fine n probably smell nice..

Thanks Stoney... appreciated. They smell delicious.

How are they now?

Over a year later hopefully it was all smoked up and enjoyed!

I know I was being sarcastic.
