Guys im growing 6 plants in my balcony wich is protected by large glasses so i got a greenhouse xD, and all my plants are in vases.

The water im using has ph 6.3

All the newer leaves are growing yellow and deformed, the deformation i thinks it's because of heat, stress 5 days ago temperature were between 13ºC-14ºC at night and for 3 days they dropped down to 2ºC-4ºC (glacial wind come to my country)

Now the temperature is stable again but my plant stills bad :'(

Note: 1 week ago i sprayed my plants with a solution of 2 parts water and 1 part alchool to kill spider mites.

the stems are also turning a little bit purple, any solution guys? :s
 
Ya, temps not good, but that's not your problem.
Are you feeding anything yet?
Those look like pots, but you call them 'vases'.
Do they have drainage holes?
I don't see any perlite in there, and your soil looks saturated.
BTW, try to get your PH up a little also. (6.5)
Not too bad now, but if you continue watering with low PH like that, you will create problems later.
 
Atm im not feeding anything but i got some fertilizer npk 2-4-4 i dont know if it's good or not to give it to the plants also i dont know the quantities :/

my soil has some perlite in it and the pots got drainage holes
 
So, I must leave all the newer leaves dry out? in my other plant the older leaves are starting to get affected too :S
 
No, not the leaves, your soil.
Your soil looks like it's still really wet, and Cannabis likes to dry out between waterings.
It doesn't like constantly wet roots.
The yellowing is because they are getting hungry, but again, try to get your PH up a little.
 
is it the the first you use this alcohol solution?
some plants are very sensitive to alcohol
it is really difficult to say sth.
old leaves healthy?
 
don`t use alcohol it fuck up your plants.
looks like your ph fluctuates too much
add baking soda to raise ph
 
Looks to me like it was sprayed with something it didn't like at all coupled with the fact it was stressed from the low temps.

Is any new foilage growing out that is normal looking? Or does the new foliage look the same?
 
All the new foliage is grwing yellow or not growing at all its a little stunned and the older leaves are now starting to get all affected
