ph been dropping with low ppm... did a rez change been kinda of steady around 6.0. It dropped back to a 4.5 after about three days. Mixed stinger nutrient solution and just topped it off. Temperature a steady 74-75 degrees. Rez temp around 66-72 seems to not be drinking much either. Humidity has been a lil high around 70% lately but dropping to 60% now.Anybody know what’s wrong?

Have you checked your roots? Focus on res temps here. What was your starting EC and what is it now?
Rez temps have been around 66-72. Not sure what my start ec is. Just got the meter a week ago. Roots do look prett good. I a using Hydroguard but not sure how much it’s helping.

Take a picture of the roots and post. The hydro guys will be by and check them. The 72 raises concerns. From personal experience.
This morning I checked it was 64. Will take roots pic in a few

It's not drinking now because your ppm/ec is too high. Look at the claws.
What for nutes are you using?
Was there anything wrong with the plant when you swapped your res? Just curious as to why you did a swap and didn't just bump ppm if you thought it was low.

He’s saying low ppm but hasn’t given a number.
Fox farm nutrients. I changed it cuz my ph was goin crazy. I made a stronger batch of nutrients but I only topped it with it.prolly should just empty and refill.

I don't run with the traditional hydro method for that reason. You can try a res swap but drop your nutes a little.
You think I need to drop the strength. It was less than half strength I think before.

According to your foliage pic, it's overfed.

Your ppm meter is calibrated ok?checked it?
If my ppm meter shows 124*, it means x10 which would be 1124 ppm, just a thought. Maybe not in your case, but check, because my ppm meter works like that.
At 124ppm theyd be starving to death

Wish someone made a chart like this for Coco.
Run-off EC for my run has been consistently lower than what's going in and just for kicks I checked the PH a couple of days back, had risen by 1.5 points over what went in. Going by what I'm inferring from above, that's good, right? Feeding twice a day, 2 gallon fabric pots, 400ml x 2 per feed, 5 weeks from seed.

With coco you don't need to worry unless EC is coming out a fair bit higher.
Sounds like your set up is going as it should be.
