This is a picture of calcium deficiency. If this is what your plant is doing then... maybe some cal mag.

There are also other reasons why you could have a calcium deficiency. For one, if you're using RO water then you obviously have much less, if any, calcium in that water. Not sure where you're drawing your H2O from. Also, and I feel like a douche mentioning this to you, but if your water isn't PH'd correctly then it could lead to what seems like all kinds of different nute problems with differing plants. Sorry if this is really elementary information but I would be remiss if I didn't add this.

I use tap water. Noticed my ph pen was off slightly when I calibrated today. They r due feed tomorrow but this plant only 1 of four showing it. I have cal mag I will add .5ml/l tomorrow and ph to 6.8ish. Here's a pic I really don't want this to spread! 
Thanks for the quick replies so far guys!
