If this is on the lower branch, it looks like Magnesium deficiency. What kind of water are you using? If it's processed or RO, it may be lacking in some of the core metals. You'll have to add CalMag+. This is true if you're growing in coco too. My understanding is that you have to use CalMag more often than not. You could also use epsom salts, but I don't know the dosing to do this.
How is the dirt, is it drying out completely before you water again? Those leaves are bending down like a claw like over watering.
I know there will be some argument from others, but are you checking your pH? I pH my nutes to 6.0. Some people say you don't have to check in soil but I don't see how you NOT check. The nutrients are only available in certain PH ranges, and I've seen people's water come out of the tap as high as 8. I would check your PH as well, and use a meter. I know they're expensive but if it fixes the problem, it will be worth it.
You're hydro guy may give you a small sample of CalMag if you want to try it out and see if it helps, it takes a week or so to get over a magnesium deficiency.
