that's too bad this post used to be in the grow faq's section here and was so much easier to use ,i used to refer to it often
Thank you I now have hope. I know I definitely have no light leaks and Im on 12/12. Im getting my temps fixed and hopefully this grow works out.you will be ok if u sort ya temps out becuz u have put ya plants back buy not havin right temps they will be fine also u have 2 make sure u have no light leaks from anywhere when its the dark time as this can also confuse them make sure u give them 12 on 12 off as they have 2 be bang on you be ok i no people had the same prob and still had a good result
Thanks robert. Yes the plant are deep purple this round I think its because of the temps. I ran my exhaust back into the tent and its up to 70F during the day but it still fell to 51F last night. I need a small space heater but my main concern is running up my electricity bill.
51F was only last night. There was a two week period it was getting down to almost 40FIf a strain that normally does not turn purple due to genetics turns purple then you are almost certainly dealing with a Phosphorus issue. When temperatures get to 50 degrees F. or below it will inhibit the intake of Phosphorus. If you only had one night of 51 degrees F. that should not have been nearly enough for the coloration seen in the pictures.

You may have something else going on but considering your plants are obviously Phosphorus deficient I would say that would be the most likely culprit. When Phosphorus deficient the edges all around the leaves or half of the leaves can be brownish and work its way inwards a bit causing the part of the leaves to curl up in the air a bit.On a side note besides the slow growth what is the cause of these problems with these two leaves??
Sounds about right. Ok so the first pic is do to a phosphorous deficiency which is caused by the low temps I almost have the temps right so that problem is just about solved. What about the second pic?
