I'm sorry but it isn't a severe problem as you said, I hope they're going to be fine. I think your analysis is sensible, intellectual, and I agree with you. I think plants are very easily to be burned at flowering stage, and we don't have to feed them every time with heavy fertilizer, such as 800-1000 ppm(1.1-1.4EC), and as my observation, water them with 400 ppm(under 1EC) solution every time maybe proper(I'm using peat-perlite soil mix) , commercial productions' feeding chart is over-fertilized schedule, some said plants will focus on producing flowers at flowering stage so those leaves aren't the point anymore so they are going to be vulnerable.
