Hey bud, yes 6.5 is not good. Here is a better chart for just hydro and you can see 6.5 is too high and locks out many things. You should aim to float your ph up and down between 5.75 and 6 for optimal uptake. 6.5 Misses Mag, Boron and Phosphorus completely.

The plants look a lot better now and have stretched in flowering nicely, thanks for the feedback. They are in soil so 6.5 should be hopefully fine
so what exactly did you do to fix the problem?? im still having the same issues..

In my case the light was stuck to the bar at the top of the tent with masking tape and it became loose and the light got too close to the plant and stressed it. Once I raised it and stuck the light properly 20 inches away from the plant it recovered

I'm on a covid budget too - but masking tape (most tape) will loosen because the light's heat will soften the adhesive.

Try some paracord (or other strong-ish cordage) and learn a couple knots.

I have a light hanging on black paracord (lights out or send a pic).
There's a Bowline on the top bar, an anchor hitch on the bottom, and a trucker's hitch about a foot above that for adjustability.

These knots are are basic, but will get you through 99% of your knotty needs:
