I need help with my plants, i dont know what the problem may be.


Setup:
HPS 600W 24/7 thats been on since they where seedlings.
Good Ventilation, big space.
The plants are about 40-50 cm from the lamp.
The temp is about 25-28c.
They are being watered every two days.
The soil is proffesional growing soil. .

Everything has been going fine until this last week, they start to dry at the end of the leafs, getting yellow, and stuff like that.

Strain is mostly white russian, but there is som kush, blueberry etc.

Here are some pictures on the symptoms
