Leaf Problems HELP!

Ok two out of my three plants have run into some problems and I need help to identify them and maybe some advice to correct the problem. One of the plants leaves are curling up and are dry and snapping off, after reading I think it may be a heat problem but I have no idea how because they are under floros and have a fan running on them. My second plant is looking better, besides the little purplely brownish spots on the first set of real leaves. This plant is my favourite so Id really like to save it... oh and the baby leaves in all my plants are yellowed and in verious stages of dying, but from what I read this is normal.

What are you feeding them? What kind of lights? How often do you water?

Not feeding them yet, but the soil has some nuits in it, 8-12-8 I think, It said like 9 weeks worth or something like that... Umm they are under two florotubes and I water them when they get dry and mist them when Im bored...

Chlorine in the water,spraying whilst lights are on,tap water

looks like its been resting on a flo lite, has it?.
or its been damaged in some way.

do you stand your water before using it?.
i get mine from the rain outside, i collect in a dustbin.

Ok, I was using water from a water dispenser, with "Natural Spring water... it said it was Ozoned but there is still some chlorine in the ppm about ___. I was thinking that it was because I misted the leaves under the light and the droplets maginfied the light and burnt little dots, but I wasn't sure, If this is the case should I prune these leaves off... they seem to have paled and yellowed while the top remain healthy... thanks for all your help, Do you think they'll make it?

26ppm on the Cl

The present temperature difference between day and night may cause some difficulties. At day temperature may go up to 30 degrees centigrade, while temperature at night may be only 17 degrees centigrade.
Through this, plants have to evaporate too much moisture in too little time when facing day temperature. This may cause so called burning tops. Leafs will show dry brown edges (or they get all brown) and they curl.
New tops will grow, but it will slow down the growing process enormously. It probably takes you several weeks more before you can harvest.
The maximum difference between day and night temperature must only be about 5 degrees centigrade. So it is advised to heaten up a little at night.
Good luck.

Thats prob it, my room is fucking freezing at night, Ill keep a heater in the closet, thank you!

ohh man of course in a such a cold room you may have those kind effects but I am sure after doing something it will turn into normal.

id add a warm mist humidifier for when they sleep, it will warm the space a couple degrees depending on the size, and add humidity... and they're only like usd 20$

I just have a IR lamp keeping the air warm, seems to be working too, much warmer in there then in my room now, Im thinking about sleeping in my closet haha
