white tips, help please!

my plant is 2 weeks into veg using 150watt hps and 4 26watt cfls
temp around 22 Celsius /72 Fahrenheit
using miracle grow potting soil
haven't been using nutes, only distilled water and tap water

Any help is GREATLY appreciated

anyone?... its getting worse and i dont want my pretty girl to die
I flushed it completely today hopefully it will improve over the next few days

It's nute burn from the MG. Use water only and keep on going.

agreed... Miracle Gro can be way too "hot" for small plants... just use plain water until you see a clear need for nutrients.
