Looks like a Magnesium deficiency. Most likely it's related to your PH being out of whack, or using R/O or distilled water and not adding Cal-Mag. Make sure your PH is in check and, if not using tap water, add a Cal-Mag supplement and she'll recover but damaged leaves will not.

Thanks mate my ph is always good.
I did have them in a cupboard with no air flow and we have a really hot week of 40c plus could that be the problem.
There in the grow room now with 2 intake fans 3 pedastol fans and a carbon filter so my grow room is well ventilated and lots of fresh air.

Over all it will bounce back??
Plus only 1 out of 4 had a few bad leaves.
