That's the exact opposite of what they need looking at them pictures. You're running heavy on the nitrogen and it looks like you could have another slight problem which has stemmed from that. But those tips curling under are telling you the nitrogen levels are high. Upping the grow feed would be a disaster for you.
E2A: Ok maybe not a disaster, but it'd be shit put it that way. Too much N takes away so much quality from your finished bud. I'd always have the N on the low side in flower just as a precaution. It's easy to treat a yellow leaf... it's not easy to get back the ratio of bud to leaf and stem... or the hours lost to trimming all that shit.
You need to concentrate on upping your night temps for at least a week solid and seeing how they are then. And drop a mil of the grow feed.
With cold temps it makes it hard if not impossible to judge how they're being fed and whether they like that or not. The tips curling down is a sign of high N levels, but it's also a a possible sign of cold temps. But likewise the paleness of the lower leaves can also be a result of the cold temps, or it can be the first sign of N def. It's why, especially if you're having a little problem, it's dead important to make sure the night temps stay up.
