Went from praying hands to the claw. Humidity jumped to 73% had light intensity issues early. Plant freaks if it is closeted then 24” at 40%power . I use a meter but I was only inserted maybe mid point. I use fox farm happy frog and nutrients also. Watered roughly every 4 days during the flower before this. Leaching 10-20percent

Id back off the nutes a bit. Looks like its getting too much N.
What nutrient line are you using? You may be able to control how much N you are feeding by tweaking the ratio slightly

Honestly, they look like they are overwatered, the leaves would be shiny and very dark, with tips clawing, those look more droopy than clawing. With nitrogen toxicity, the leaves will still stand up but the tips will turn down. 
Keep in mind that some plants will droop at lights out or on.

I use the Fox farms trio and have followed their chart. These pics are 3 watering ago. Two watering ago is when I realized I had a problem with humidity and the room was musty. Dehumidifier fans added at base of plant let the plant dry to a reading of 2.8 deep in the pot and watered no nutrients and not much change

FF feed schedule is a bit much most time, lots will feed, water, feed, water. Or feed, water,water. FF is pretty salty, are you doing their flush schedule as well? Salt buildup will tank your ph and spike EC also.

Those early pics look great!

Reading back, I just caught your humidity, good chance the high humidity shut down your VPD and since they weren’t drinking, the roots stayed wet and plants got the droops. Adjust the humidity and give them a couple days to dry back and see if they don’t get happy again.

I have not flushed but leach 10 to 20%. Soil was reading alkaline so I added less than an 1/8tsp of citric acid to the water because the water read alkaline as well. So my previous statement is a little off on no nutrient in my watering last time which was Tuesday morning. Meter was in the green reading at a 5 this evening before the light shut off.
Thanks and I was real thrilled until this happened. As soon as I thought I understood her she said NOPE

I’m thinking I should have waited one more day on this last watering and let it drop into the 1. Something vs the 2.8 just into the dry range. Thanks again for the advise.

Meter was green? You’re not using a soil probe are you? If so, they are fine for moisture but terrible for PH.

Bobby, the green is in reference to moisture on the 3-1 probe. The attached picture is the current ph of the water I will be using to feed once I get the moisture down. How would you suggest getting an accute ph. I’m at a loss as to what happened here.

@BobbyDigital right before lights out. Moisture said 2.8 @Growdoc @Solidgold91

The best advice I can give you is to throw that meter away and learn to judge by feel when they get light.

Those soil probe meters are totally unreliable for pH. You have to get more dialed in and more accurate numbers. I, along with most others here, will suggest you look into BlueLab or Apera meters. They are about 10x the cost of that probe, some much more, but you will thank yourself later.
Also, as mentioned in another comment, the FF Flush. Fox Farms nutrients are notorious for salt buildup at the root zone. This can cause all kinds of issues if not addressed early. Watering and feeding to runoff ain’t gonna change it. I mean our blood is constantly flowing and we can still get bad cholesterol buildup right? So, the easiest solution is, per the FF feeding schedule, the FF Sledgehammer flush. This will “flush” out the excess buildup and return your soil to a point that nutrient uptake is optimal.
You aren’t in a bad spot. A little darker green and minor clawing, but catching early, taking the right course of action and she won’t miss a beat.

@Borderryan22 thank you for the advice and I will look into the other meters and look up that flush you referred too. Thanks

Yeah, that’s worthless for PH. The moisture probe worked well and taught me how the pot should feel when it’s dry. I would water when it got down to 1. I cut the PH probe off of it so I wasn’t stabbing two probes into the soil. Eventually you learn the weight of the pot and see the signs of the plants for when they want water.
