Drooping leaves, caused by cold water??

Hi everyone, well I've got some more problems with my babies.
The leaves are curled under with would suggest to be over-watering although I did not change the irrigation cycle.
I'm growing in hydro, using a top feed system.
I had a light nute burn a few days ago so I flushed and lowered the nutes, worked fine.
I also had a bit of an overheating issue (the days are getting warmed again) so I turned off my heater which blew warm air onto the nutrient reservoir, could this by a result of the water being too cold?

Additional specs:

Room temp: 68 - 85 (20ºC - 29ºC)
Water pH: 5.5 - 6.0
Nutrients: Sensi grow from AN
Strains: Critical + AUTO; Ultraviolet AUTO; Malawi; Zamaldelica

Not if your low temp is 68..should be fine

hes growing in hydro. Yea you need to monitor your resevoir temp as well, I can't tell you what the range is for I'm a soil grower but I'm sure it wont take but 2 mins to google and know what you need to. hope this helps man

The temps range from 68 to 85 where the plants are growing, under that table (where the reservoir is) I suspect its about 10 degrees lower

Any help??

My young plants drooped, like those in your pictures, when they needed watering.
It always amused me how quickly they would perk back up, once a little of the reservoir mix had been poured on the base of the stem.

I was feeding them only water to flush out the medium, had some nute burn, I changed the water and gave them a 1/4 strength nute solution I'll post back with news

Any improvement ???

To elaborate on my earlier post
I had just put rooting sponges into pots of clay pebbles - and was feeding from a reservoir with a pumped irrigation system (Atami Wilma 20).
The roots were so small, at this point, that they could only get water that travelled VERY close to the sponges.

For a week, or so, I had to hand pour res mix directly onto the sponges.
It was easy to see which of the young clones needed personal attention
because they drooped badly (just like yours, in the pictures, above)
but quickly 'perked up' immediately after nutrient solution was poured onto the root ball.

After about 10 days the roots had spread enough to take water from any part of the pot
and the drooping stopped completely.

Sorry about the late reply, completely forgot to check back on this thread.
Yes, they are doing much better! My autos are almost finished (another three to four weeks) and my sativas are growing fine...
...Check for yourself



Sorry for the bad pictures, only had my cellphone with me
