Welcome to the site. Hope you enjoy it here.


Looks to me like you have a Cal/Mag issue and a shortage of feed.

Your pH is a bit on the alkaline side so I wouldn't use the 'lightly top dress with Dolomite' solution. I 'd foliar spray Calmag especially if you can get a mix that includes Boron. (Ca/Mg/B).

Feed more, make sure your feed is not running straight out of the bottom of the pot before it can do any good. Put a shallow saucer under if drainage is too quick.

Bye from the Land of Oz ...

So did a soil test

Ph 6.5
Phosphorus = Low-Medium
Nitrogen = Medium High
Potash = Very low

Now im just feeding it with Water at 6.6-6.7 ph water, nothing else just trying to flush it i guess what its called until the leaves start going back to green

any ideas?

Classic calcium deficiency. Get your phosphorus up. Do not apply magnesium. If you want to put on magnesium EVER, apply it as a foliar. 1% epsom salts works just fine. Magnesium is very mobile, the roots will take what they want, no worries. 99% of the time, excess magnesium is the problem. Folks apply it and see results, yep, but it is a double edged sword. You are pushing potassium down, when in fact you have plenty of Mg or even toxic Mg! Not linear thinking folks. The reason this happens is usually due to low Ca and low P.
