Your plants are not getting enough potassium!

This is very important, especially during flowering.

The photo above is experiencing a potassium deficiency, whih looks exactly similar to your plants. I suggest changing your nutrient solution. You can feed your plants seaweed meal, or, feed them old smashed up bananas. I would just start out by getting a nutrient that is a little higher in potassium, and go from there. They aren't dead, yet, but get this fixed quick!

Happy growing my friend

yeah you either have nute lockout or potassium deficiency it looks really bad. just a long shot but try adding a teaspoon of salt to your next watering and see if its an mg deficiency.

^ Agreed.

Definitely looks like a Potassium deficiency, but it may be a Magnesium deficiency as well.
