I like your method of less is more. Instead of giving your plants full dose of nutrients in 1 douche, but to half the strength and water 2x a week. That's what i determine to be ideal.
But ya, other than a few mid plant leaves yellowing up a bit, your looking ok so far. If you just started flowering, i would reset your soil now, so that you reduce the risk of problems later. By that i mean flushing your soil with pH corrected water and then carrying on to the finish.
