What is wrong with my plants?

Hi, I´m in end of second flowering week and my plants worse and worse. I mean they started to stretch and their leaves does not look healthy (not firm enough and kind of light green on tops).
I grow CBD Blue Shark and Candida CD-1 strains. There is 4 plants in 80x80cm tent with A-wings reflector and 400W HPS which I keep around 30-40cm from plants (they are not same size).
Please could you give me some suggestions? Thank you.

Over watering , light burn, heat stress.

More pics and more details.
Thank you. It is truth that I have changed watering ammount and schedule recently. I did water them every they a bit, just by my "feeling", but now I have changed it to every two days and I water them till I see some water run out off the pots.
My light is turned on in the night and in the room is temperature about 22-24°C. Tent is standing close to the window, so air which is sucked to the tent can have around 20°C to 21°C. I have measured temperature on plants tops and it is between 25 to 28 °C.
I use active exhaust, but I dont know how mouch airflow is there, because its, regulated and also ther is a carbon filtr. But I guess around 150m3/h. I use also small fan inside a tent, but only when light is off. Plaese what kind of other details you need to know and what pictures?

Your plants look fine to me except for the overwatering. They just need to recover from that and I bet they'll perk right back up. I think you should stop watering altogether until the soil is dry for the first 4-5cm of soil. Maybe even a bit longer. Then resume a proper watering schedule.

From what you have said, it doesn't seem that the temperature is am issue here. Nor are there any obvious discolorations to indicate a nutrient/pH problem. Growth seems fine. They're just oxygen-deprived from too much water. Good luck!

What type of soil are you using?
I´m using mixture 1:1 of peat soils - Plagron grow mix and Canna profesional+
Also I use Biobizz fertilizers - Grow, Bloom, Bio-Heaven and Top-max according to biobizz schedule.
I water by still tap water with bit of citric acid and above mentioned fertilizers.
Original Ph of water is 7,7 after fertilizers and citric acid around 6,4

I probably found a cause of the stretch and light green colour. There was a light leak in intake air tube :(

also, keep your fan on in the tent.

Hortiman,
remember that overwatering refers to

NOT how much water you use at one time
BUT to the frequency of watering (by Not allowing the roots to get air)
