4th indoor grow and this is the first time with this issue. Same soil same light same nutrients 
Any advice would be greatly appreciated. 2 plants are 7 weeks old white widow auto. The other 4 are 4 weeks white widow auto. All beans came from ilmg just from a different order
The pic in the middle with the dark leaves looks like nitrogen toxicity. Do you know your PPMs?

That all looks reasonable. I would suggest a PPM meter so that you know how much salt you have retained in your soil. It’s hard to make recommendations when it looks like it might be nute burn and PPM is not understood.
You mention 6.5 pH, which if a runoff measurement is good. Is 6.5 what you have going in when you feed, or is that a runoff pH? I would expect that runoff is probably lower than 6.5. Is runoff 6.5 across all 3 plants?
Just checked with meter it’s 6.6 before feeding

Okay. The runoff pH is important too. I expect it is low and you might be having lockout issues among your plants too. If your runoff pH is very much outside 6.0 to 7.0, then you can also have serious problems.
Runoff pH and/or PPM being out of range is what I would suspect given the age of the plants. Runoff pH should be between 6.0 and 7.0, and PPM should be ~1,000 at this point. pH is probably low and PPM is probably high. You’ll need to check runoff pH and PPM to verify and then take action to correct it.
