Heeeeeelp!!!!!!

Guys I need help URGENLY with the following:

In my Vegetative room I have three stations for growing. On the fotos you will see that it looks like the leaves are drying/dying. These are all clones from healthy mother plants. This only happens at one of the growing bays. At the other bays the plants are perfect! My growing medium is 50/50 potting soil and palm peat. At this early stage i do not add any nuts to the water....so clean water was given.

In my flowering room (which contains 12 plants under 2x400W HPS (son-t) lights)
I have two plants of which the tips of the leaves curl and die. see fotos. I have a suspicion that it is a potas.and Phos. deficiency?......pls help

The flowering room looks to me like nute burn/light/heat burn... one of those, check all, flush plants if you believe its nute burn also check pH.

the veg room...
that looks to me like some type of heat issue as well but not 100%

Yea, both look like heat issues man, that would be what i would check first, how close is your light to the plants?
