  2. What are your temps with lights on and off?
     
  3. when on about 28-30 Celsius (its is pretty high), when it get too warm i open the closet, off is about 24-26.
    Is too high temps can make the plant purple?
     
  4. Overnight temperatures below approx. 15 Celsius can cause plants (and the buds) to form purple areas. If this is the issue, as far as I'm aware you have nothing to worry about. However, you will get some cool looking plants and bud!

    Good luck with your grow :)
     
  5. If leaves are curling that is usually some kind of nutrient deficiency. As to which kind, I am unsure as I'm not an expert and only know so much about growing.
     
  6. i have just watered them with a little NPK nutes, i will see if the tips will stop curling.
     
  7.  
    Have you pH'd your medium?
     
  8. Yes its 7.2-7.0
     
  9. What is your medium anyways? 
     
    7.0 is too high for either soil or hydroponics, so you should really adjust that accordingly. It's around 6.0-6.5 for soil and 5.5-6.0 for hydroponics.
     
  10. Its soil, i will look onto how to lower ph at the soil, can you recommend me any methods for soil?
