Calcium deficiency or Nute block

SOS! So i’ve been having these orange and brown splotches pop up on my leaves, fan and sugar alike, and I’ve done a lot of research and I just can’t seem to figure out what’s wrong. Where I live the water is really hard and I haven’t been treating it as such for this whole grow. I’ve just been letting it de-chlorinate by sitting it out for a day or two and then water with that. For a while I was adding water soluble nutes like Grow big and Tiger Bloom but have stopped using those recently. I thought at first it was a deficiency but after looking more into nutrient lock and how that works I thought it could be that so I’ve been giving my plants a good flushing, their second one was yesterday, and I’m still seeing these pop up everywhere! Any advice would help I’m sure. The pH of my hose water is also around 7-8 pH so i’ve been using some pH down to get it around 6.2-6.8 but thats only with in the past week or so I’ve been starting to pay attention to my waters pH levels and whatnot.
