Cal issues?

Hi all, sorry I can't upload any photos atm as lights are out but will do as soon as they are back on.
Basically I'm in the 2nd wk of flower and my plants are showing what I believed to be cal/mag deficiency, we do live in a relatively hard water area (230-250 ppm) @ 8.4 ph,
I'm growing organically and have been lowering my pH using bio bizz organic pH down to(6.5ph) I know it's soil and it sorts itself out but couldn't see any harm in giving it the correct pH.
Temps are 77 lights on & 70 lights off, 53 rh, watering every 2 days as soil is dry (top 3 to 4 inches) pots are lighter too.
Anyway I'm wondering if having slightly hard water could actually be causing an overdose of calcium instead of what I thought was a deficiency and i turn causing lockout?
Is 250 ppm tap water too much for them?
Plants are light green with some browning on the leaves, I've had her under a scope and can't see any bugs.
I do have an ro system running in our house but didn't want to go through the shit of adding all the cal/mag etc, wondering whether to dilute my tap water down with the ro water to bring the ppm down. What you all think?

I have hard water where I'm at in the Midwest as well. Extra Calcium is definitely a probability
250 ppms in a vegetative phase isn't too much at all.
Using the R.O system and just adding a light nutrient feed at a quarter strength and using that as a base to see what effect it has on the plants sound like a good direction to go....hope it helps

Cheers pal, things aren't too bad I just want to get things properly dialled as my auto's will probably be ready in 6 to 7 weeks and don't want any stalls

Here's some pics of my auto plants exactly 2 weeks into flower today, they aren't looking too bad just want to to give them the best I can. Some purple on the stems aren't really worrying me as I've seen this alot on this strain so I'm thinking it's genetics, they are starting to droop a little as the lights are due to go out shortly. You will see some slight nute burn on the tops but I've sorted that now, I was just dialling my organic nutes to see where I should be at.

Looking like thier coming along ...the purpling could be a slight mag issue but it's common ...or your genetics ...look good tho champ
Check out YEILDSOURCE on YT he's pulling 3quarters of a pound regularly with autos ...might be worth you checking out ...keep up the work my guy
