I've been following this forum for sometime and have been super impressed with the quality information and direction provided by the members here. This information provided has inspired my to try my hand at growing my own stash.

Things have been going great until about 3 days days ago when my plants leaves began to droop and curl upwards from the side. At first I had hoped it was the result of light burn / heat stresses as my plants where only 6" from the bulbs and the temp was 30*C (85*f) at the canopy. But I lowered the plants so the canopy is now 14" from the bulbs and the temp is down to 25*C (77*f). I plan to move 4 of the 5 stongest pants to 3 gallon pots but hope to get this situation resolved before the transplant.

I'm just a noob, but I'm thinking that the cool evening temps at 15*C (59*f) or the small 16 Oz cups may be the at fault. I was hoping to see some pre flower sex signs before the transplant but that may not be possible.

The grow conditions are as follows:

Plants: 3 weeks old from germination 4"- 6" tall

Strain: Bag seed supposed to white widow x
Northern lights

Light: 8 16w house hold led bulbs
4 2700k and 4 5000k
18 hours on 6 off

Soil: Seeds were started in Peet pods then
transplanted to 16oz solo cups with
Miracle grow seed start 0.03/0.03/0.03

Cabinet: 14" deep, 28"wide, 54" tall
Temp lights on 25*C (77*F)
Temp lights off 15*C (59*F)
Humidity is 30% lights on and 55% off

Water: The plants are watered every second or third
day as necessary. I water till there is run off
and wait till the soil on the surface is dry and
cups are very light.

Ventilation: 120 mm computer fan for circulation
(Plan on installing another 120mm fan
as and exaust on a charcoal filter it's in
the works )

Nutrients: None at the moment

Ph: Run off water is 6.8

Try to increase humidity when the lights are on to at least 50%.

Also, I think it's transplanting time.
