Leaf Curling Problem! Pics

So I have some Lemon Skunk and Jack Flash clones (along with many others but they don't seem to have the same problem) and when I added my 1000 watt MH to my tent to warm it up a bit the leafs on some of the plants started to curl up like a venus fly trap or canoe... I think it might be heat stress and I have added an air cooled hood to my tent and that dropped the temps a lot but I just wanted to make sure and get some other opinions...

It might be a nutrient problem too because I forgot to top off my res for a while and the PPM was increasing every day because the plants were drinking faster than they were taking in the nutes...

I am growing in Hydroton in an Ebb and Gro system and have a total of 18 plants right now... the only ones that seem to have problems are the Lemon Skunk and Jack Flash right now... I am using Humboldt Nutrients Oneness program with a little bit of Hygrozyme and some MagiCal that came with the system...

PH has been right around 5.7-5.9 so I don't think it is a PH problem...

The last 2 pictures of the bigger plants are of my Purple God Bud and I think that it has some kind of nutrient problem but I am not quite sure... It could just be the new growth?

Any help would be greatly appreciated!

Thanks,

I think they look alright, I've had plants with leaves that curled at the edges like that while growing under a 150w CFL and they turned out fantastically, amongst the strongest plants in the grow.

None of your plants look singed or nutrient burned or stressed so relax and keep doing what your doing. I'm sure you'll be fine.

Thanks for the reply! I am probably just paranoid because this is my first go around with hydro and I am still learning...

I also dig your profile picture...
