Turn your HPS off and take pics with just fluorescents or something. You can't tell much by those pics.
Also, a little more info would be helpful; medium, nutes, schedule, temp, water source, strain etc...

I'm not familiar with that strain, what's the indica/sativa ratio?
Are you running CO2? If not, your daytime temp is a bit on the high side, but workable. The main concern here is your day/night temp differential, that's a big drop, you should aim for more like 10-15 degree dif.
I assume you're using Canna's coco line of nutrient, but the only thing I can really tell from those pictures is that there appears to be some water stress but that could be a strain thing also...
I'll check back tomorrow

using this guide id say that has Nitrogen(N) deficiency. what do u think???
had a bit of a problem with my inlet so may not have been letting enuff fresh air in. but that sorted.
re-filled the butt sunday n checked it today and nutes were 1.6/18. so lwered them to 1.4/1.6. p.h is 6.4 thats fine. temps are 60/74 off/on, ut only since i turned 1 of 3 600w off today. other wise 60/84. humidity is fine 40%-60%. . its my 2nd attemped. 1st was a mess. always had a prob with temps. fitted some tubular heaters since to keep off heat up. hope its not over watering added some more fresh water tonight. dis-colouring has started on some of others. help me out lads please...

It looks like you have several things going on here, and judging by your EC, I'd say lockout is the probable culprit. It does look like you're running an N def, but probably also Phosphorus (purple stems and dark leaf tips). It's really hard to say, it looks like there's still an HPS light on in the room, so the new pics don't show the true color of the leaves. I'd give them a decent flush and mix a fresh batch of nutrient at half strength and see how they do.

after flushing yesterday and checking tonight e.c was 1.8. flushed again tomake it 1.6. also turn a 600w off. so iv only got 1x 600w running so now temps are 60 off 72 on. i had 3x 600w on and my inlet got blocked plus think i had nutes too high........think this was my down fall???

Much better. Looks like classic nitrogen, but I'd say your cause isn't underfeeding, probably over watering. Give them a good flush (once they've dried a bit) and start back in with a fresh batch of half strength nutes.

These pictures are a little dated but I was wondering if you guys think its a different strain or nutrient deficncy

Feed that girl! Also, over watered. Coco coir on its own is a little too moist for my taste, it should be mixed 50/50 with hydroton.
