need help guys

I just noticed yellow streaking in my plants. Its all over the leaves, but not yet on new growth.
Its not spots, its like someone tool a yellow sharpie and streaked on the leaves.
One thing I did notice today was the room got down to 66 degrees. Would this cold do that to them? Normal room temp is usually around 75.
Using the same nutes I have been with no former probs(cutting edge solutions)
Also did have a hard time getting the ppm down last time and but did end up getting it at the max number.

Im going to try and get a pic up. Thanks guys

PS growing in fox farm soil

Heres a pic, see where it looks like the lights are shining on the leaves? Well its not the lights.
Also notice the leaves are curling kinda like a taco on the edges?
Please help, Thank you

I think it has something to do with nutrient defeincy.
Some one else will hopefully tell you what kind(Why do you have two of the same posts of this).

i also had some issues with tacos curling i thought iwas a light defficiancy, could be but i just made sure that the leaves werent getting to hot from the MH lamp and that there was plenty of wind blowing aorund. also try some foliar feeding when u turn the lightd off, also check your soil...is it to dry?

What exactly is your nute regimen. What is your water source and how "clean" is it before nutes. My plants do this periodaclly as well. Not the temp I can tell you for sure.

Here is a super edcucational link on nute defficiancy. Typically intervenal yellowing is Mg def. Educate yourself on that subject here. Hope it helps, Happy Harvesting!http://4e.plantphys.net/article.php?ch=t&id=289

imo: nute burn..

when in doubt, cut out the nutes for a week or two,
go straight phd corrected water. and see what happens.
