2 quick questions

1. My plant is 6 days old and is on a 24/0 light schedule. the first two leaves though are warping. they shrink in a little in the middle so it sort've looks like an 8 or an O wearing a really tight belt. and the tips are a pinkish color. why's this happening?

2. I plan on vegging for 5-6 weeks. how long is the flowering process and how will i know when to harvest the buds?

What kind of light, growing medium, pH level, nutes, humidity, and temperature?

you might be over watering them.. and the first week you should probably water only twice, maybe 3 times..
let the soil dry and feel that it's crispy and water the day after..

also make sure they are not suffering from heat problems.. and i hope your not giving them any nutes yet..
