Hey dude.
congrats on getting your grow started.
I can't see any white hairs as I can't zoom in on your photos. They are taken too far away from the plant.
I'm a little worried that your plants are over 2 months old and so scraggly. I would expect them to be much fuller and stronger.
Understandably your plants look like sativa and mine are more indica. Howerver, if I veg for another month my plants will become about 3 feet tall.

Can you give me a full run down of your set up ? Lights, soil, fans, fresh air circulation, etc.
This is my second indoor grow and my plants are 4 weeks old. I'll give you a pic so you can compare.
You can check out my grow on the 'indoor growing' section. I have 2 grows, the first one is called 'testing the Pro-Grow 260'
