Strange drooping

Hi all, back again with problems. Basically every run I over water, this run I've been very careful and waited till pots feel light, generally been 3/4 days. Currently 3 autos in 6.5 l pots under 2 mars ts1000 in lightmix using Bacs nutes. Water is PhD to 6.3... problem is when I water the plants (water till around 10% run off)they droop for the next 18hours (ruffly). I've let the pots go bone dry, even bought a basic moisture meter and shows that soil is dry, yet if I water she looks like she's been overeaterd and takes ages to recover. Any ideas?

Temperature and humidity? Those moisture meters suck. Learn to water by weight.

I do water by weight, but when I came across this issue I used one to see if there was any moisture in the soil. Temps light on-25/26°c , 48%rh
Lights off 21/22 , 52% Rh... Running 18/6

The problem I'm getting is drooping after watering when pots are light

Thinking it is time to pot up; if you can’t seem to water enough that’s usually the first sign that roots have reached the edges

There autos though and started flowering. From what I've been told it's pretty pointless transplanting now as roots don't grow to much in flower

What's your water temperature?

Hmm I store it in containers in the same room as tent ,but outside of tent and the ambient temps are about 22°c. Can't say I've ever checked to be honest

Worth looking at, especially if it's stored on a colder concrete, etc. floor. I generally have my water ~63-65f degrees, but sometimes cooler water can cause difficulties.

Your temperature is far too low. Raise it to 27C and watch them.

I think Rich and hotrod nailed it, I'd pot up and raise the temps 27c or even a little higher

This is them today, temps haven't changed and they look healthy, then in 2 to 3 days pot will be dry, so I'll water and they will droop again for a full day no matter how much water I give them
