Install a RO water system, or just buy cheap 5 gallon jugs of purified water.

Edit: though before you do that I’d probably just try your 200ppm water with the nutes and see how your plants do. 200 isn’t terrible (depending what’s all in the water) and may not have an impact. Just lighten your feed.

It looks like you have nitrogen or magnesium deficiency going on in those pics. Are you growing in soil or coco? I see soil as the medium with coco nutes - just want to make sure I’m on the same page.

hahaha
im using a soil perlite+ promix
the local hydro store did not have in stock normal sensi, so he offered me this alternative told me it would do great (wrote to advance and they said i should not create a problem)

Hmm ok. I don’t think I’d make any big changes to water at this point TBH. I’m not sure I’d make any changes to anything yet. Keep doing what you’re doing and post pics again in like 2 days.

Edit: one change, start checking your pH after you mix nutes into your water before feeding your plants.
