Thanks for the replies. The temp thing is a good question as I'm been trying to get away with not having to get the extraction fan out at this stage as its a bit of a pain running it to the outside world, but having said that my temps have been going up and down like a yo-yo so I've decided to rig up the extraction fan to try and control them a bit more. I was getting up to the low 30's with lights on and down below the 20's with lights off. I was hoping to use the coldness of the surrounding room to keep my Grow tent cooler but its seems not to work so well, so its out with the fan. One thing I have noticed is that the plants that are showing the problems appear to still have quite a lot of moisture in the soil after I had left them for a few days, where as the heather looking plants appear to have dryer soil. I didn't put any stones in the bottom of any of the pots this time, so that may be having some effect on drainage.
I brought myself some Epsom salts today, should I give them a spray now, or see if putting some drainage in helps first?
I also have a Ph tester so I'll give that a go later.

Thanks
