Deficiencies and questions?

Should I add extra calmag this feeding or does new growth look ok enough to just do the recomended dose

Add some about 50-60 ppm extra. Your new growth is going to look good because the plant is robbing from the lower growth. Up the food a little and already suggested to foliar some epsom salt on there for a few weeks to see if that purple goes away.

With that kind of water..even if you have it down to 360's, it's way too high!!! There is no telling what can be in that water, so there's no telling what has happened in your grow medium. Mg certainly looks lacking, but again..it would be hard to tell you how you may correct it without knowing what's been going in, and 500+ppm water at the start may have thrown things out of whack and until you know what's in the water, it's virtually impossible to say what you should do to remedy it. Are elements deficient? locked out due to a toxicity of another element? lockout due to ph? it's hard to know as we don't know what those 400-500 ppm's consist of.

I'm looking for my water test no luck yet got it down to 360 my buddy has another filter he said will get me dowb to around 100-150would that be accaptabk e

under 200 would pass, and yes, close to 100 is fine, even to 150.

Looks like too high Cal and low Mag and S. Had very similar issues. A dose of Epsom salts would do you wonders!!

Just what I was thinking. 500+ppm water most likely contains more than enough calcium. Adding magnesium may just be the ticket. When it comes to well water total alkalinity is more important to know than pH.
