Any help guys please
Not knowing your nutrient line or the contents, it’s pretty hard to offer any kind of diagnosis. Plants don’t look bad per se but should be some nitrogen going into plants: you are seeing N def with the yellowing and a P def (or excess) with the purple hue to top leaves. Likely a def as P regulates how leaves accept light: this is why you see it on leaves closest to light.
Any time you have an issue it would be good to include a Support Ticket along with good pics.

I’m going to close your other thread: let’s try to confine to as few threads as possible in order to keep the main ‘feed’ open for others.
Why i need help
We’ve had folks on here start a dozen threads in a couple of days which takes up space that other growers need for their questions. Best thing to do is tag folks into your thread: use the @ sign along with user name and it will show in bold if done correctly. Like this:
You’ll get plenty of responses and I linked your other (closed) thread for reference.
This sums up the situation here. You’re late in flowering, and getting the older fan leaves used up. Purpling on the leaves can be a phosphorus deficiency, but being this late into flowering, there’s no recovery, but they’ll finish.
So what i can do here is just continue to feeding 1400 ppm every watering and just wait for harvest ?
And i feed 1100 ppm PL booster every watering how that can i be a phosphorus def
Just continue feeding, until harvest, unless you would like to flush.
