Is this a problem?

Arjan's Haze #2.
1 plant - 2 weeks old.
10gl DWC bubbler - 7gl in the rez.
PH = 5.6
GH 3 part nutes - 800ppm
250W MH - 18" away.
Temps - 67F night - 75-85F with light. Cool fresh air is blowing on top of the plant at all times.
Humidity - 20%

Everything looks fine, but I'm a little concerned about the curling. It has been there for around 3 days and gets a little bit worse each day. Nothing really drastic. The burn on the two tips is from after it first sprouted and I had to water (200ppm, PH 5.6) until the roots came out of the net pot.

Thoughts anyone?

Biggity Bump!

how often and how long are you watering for?

Also, how many weeks into your grow?

i would aim for 35%-50% humidity. i don't let my grow room get hotter than 78. if the fan leaves are curling up that could help...especially if you know they are not nutrient burns

I'm thinking about get a small humidifier tonight. Maybe this will help some.

It's a 10gl DWC setup, no need to water.

Forgive me, this is my first hydro grow and I must say that soil IMO is much easier, but I'm up to the challenge. Here she is around 3 weeks. As you can see there is some yellowing starting at the bottom and appears to be working it's way up. I changed the rez water on Saturday and ran a ph'd Clearex solution for an hour before I changed and added anything. I did everything according to the Clearex instructions and it didn't seem to harm anything. Since the rez change she seems like she isn't eating anything or drinking any water. Everything is still the same as in the first post besides the fact that I lowed the PPM to 325. PH is pretty stable ranging around 5.6-5.8. I have a heater in the rez which is set to 68 and I'm sure it keeps the temp within +-2 degrees of that. Tonight I saw some clear slime on one of the roots and removed it. I also added some 3% H202 @ 1tsp per gallon to help fight it. Here are some pictures...let me know what you think and if I can do anything differently? Why isn't she eating? BTW...I light proofed the rez 4 days ago because I was concerned about root rot.
