Underwater?? please help

Hey guys i have this plant, i watered it thursday i think. there was no bad signs . but yesterday it started drooping heavely, the pot was dry inch deep and it was light too, so i had no reason to belive that it is overwatering. So i thought it is underwatering. simple i watered it today. i have done it before and i have seen effect at least in 1 hour, sometimes faster, but this time it has been 24 hours and its still the same.
So my question is can it take just little longer or smth. or is it something else??

nute lock, ph off need more detail to diagnose. i can see that soil is jet black definetly full of water, going to want to let that dry out for a few days, if not emergancy transplant to drier soil, but then your just going to add transplant shock, so yea need more details to help diagnose

How do you know it was dry an inch deep? Dont stick your fingers in the soil you might stress the plant/ roots.
This is over watering, let the pots dry more before watering again.

Take another pot. Fill it with the same soil. Stick in the grow space. Water the empty pot at same time as the plant. When you think it's dry. Dig your hand down in the empty pot and actually feel the soil in the deep middle.

That size of plant doesn't drink enough water to dry that amount of soil. The second pot will close enough in moisture content. Don't water till the second has the moisture content of brand new soil from the bag. Not dry but not wet.

Second suggestion. Look into fabric pots. More forgiving on watering.

ok so it was overwater anyway?... a little tought was that this pot is too big for watering the hole pot. plant is little. ok. when i wait week or 10 days and let it dry more. and then ad little nute water for the first time , would it be ok, or is it gone plant?

It's fine. Just let it dry. If you want to add something next watering. Hit it with some compost tea. Use the heavier nutes in flower. By then it'll be enough to use the fertilizer without being burned.
