New Grower Leaves Curling weirdly

[siwk]

Hello guys. I'm new around here, and so I am in this world of growers. Recently i got a 70w hps kit and I built a micro grow. I have only one plant at the moment. She looks fine to me but i can't really teel what is wrong with its leaves. I think it is probably an heat problem... What do you think guys?

Strain: Northern Lights Auto
Temp: 23ºC (6 hours of light off) - 27ºC (18 hours of light on)
Moisture: 40-60%
Day: 22
Nutrients: Biobizz Top Max, Bloom and Fish mix (started Bloom day 20)

(first 5 pics, i used flash)

Mine did that a little when it gets hot, but 27 should be perfect. Maybe a little too much water?

hows your PH?

Looks like a little heat stress.

Thank you guys for the quick answer ^^
dazedandconfuzed the room temp is 27 but i guess the top was getting more heat, since it was closer to the light than the thermometer... I guess top will also be around 27 from now on ^^ I'm watering it every 3-4 days, as I get 1inch of dry soil.
GoAuto6 that's something I'm failing on controling, since I didn't got a meter yet. But I would say it is around 6.0 - 6.7
namvet25 that was my guess, but I'm a newbie, so i had to check xD

Another question... What do you think about the distance between my light and plant? That's something I've been wondering about :s

Maybe 1" of dry soil is not enough man. Does look kind of light green too, pH is where its at.

Mine started to do something like this. Was due to it being hot, was between 80-85F, and had a powerful fan blowing. Take the water out of the leafs. Could be something else though.

One last question guys, should I LST it, or autoflowers don't like it so much? I've been reading around, and some people say it is worth, and others don't :s
