Please help my plant to recover

Hi guys,
My plants got some problems. As you can see, the leaves are drooping and twisting.
I didn't give any fertilizer for 15 days because of a overfert suspect, then I started again with a 0.5ml/L. After a couple of days I had to transplant on a larger pot.
The ph seems fine, it should be between 6 and 7. What do you think?
It is actually an outdoor-indoor mixed photoperiod, first week of flowering now. I use a QB 120w for the indoor.

Where are you growing? In a tent or box etc?
What are the average temps
What is the average humidity

at a quick glance the drooping leaves look like over watering or too high humidity but its hard to tell you whats wrong without knowing your conditions xD

Also, could be too much nitrogen which causes the leaf tips to curl down, called nitrogen toxicity

Thank you for the answer!! I'm growing outdoor when there's the sun and it goes in a box when it's rainy.
Because of that, I'm not using an hygrometer, but the temps should be between 22 and 28 degrees and the humidity level between 50 and 70.
Yesterday the temperature increased by 5-6 degrees in only one day, and yesterday was the day I transplanted.
I don't think it's nitrogen toxicity, I used only 0.5ml of fert after many days of stop, and the leaves doesn't seem so dark as it should be with that toxicity.
Maybe it can be overwatering because of the transplant, but the leaves are twisting too, and it can't be caused only by overwatering...
