First off what week are you in? Your plants look like they were/are /has been potassium deficient. Probably mag and now they sucked up all the nitrogen out of the leaves to go along with all that. Sounds like from how you post that you underfed alot. The one guy posted about the blueberry being light feeders and you stated that that blueberry plant looks better. Do I got that right? So it sounds like you have been underfeeding the other plants and it looks like it unless your at the end of flower.
Here's what you do. Pick all of the worst sick, dead, faded leaves off of the plant. They are not helping anything other than blocking light on any good leaves you have left. DO NOT pick off anything that still has some green to it, lets not get stupid. Mix in 2 full teaspoons of epsom salt into a gallon of water for how many gallons you need to make, water that in till you have some run off at the bottom. Let it go till you need to water again. When you water again only go about 3/4 strength nutes. Im gunna say between 1200-1500 ppms tops. At this stage if you try to blast it with nutes, trying to jam nutes in that bitch your going to fry it. If you use molasses its only 5-10ml per gallon mixed in well as the molasses will stick to the bottom of your feed container AND add some microbes to that and you should be adding a little bit (small pinch) of microbes to each watering. You probably haven't added any microbes have you? Microbes are your friend. Since you say you gotta stick with those nutes you have, you should add a potassium additive to your feed for next time. Potassium is the energy element. I dont like the ratio of your nutes fwiw.
