CalMag Deff
BrediGreenystarted grow question a day ago
My first Wedding Cake still shows signs of CalMag deff and I don't know why. Already giving her 10 ml BioBizz CalMag to 3,5l water, way more then the recommended amount for deff and adjusted water PH at 6.3. Has anyone got any Ideea?

Zu viel CalMag ist nicht gut.
Die Elemente Calcium und Magnesium zählen zu den positiv geladenen Kationen - ebenso wie der besonders wichtige Nährstoff Kalium.
Nun kann es passieren, dass diese 3 Kationen sich gegenseitig in der Aufnahme blockieren, wenn sie im falschen Verhältnis zueinander stehen.
Aus diesem Grund ist es sehr wichtig, dass man die Maximaldosis bei CalMag nicht überschreitet, da sonst die Aufnahme von Kalium blockiert werden kann. Im Resultat hat man dann einen Mangel, der kein echter Mangel ist, sondern eine Nährstoffblockade, die durch einen Überschuss entsteht.
Messe den Ph wert und auch Ec wert von deinem Runoff der sollte zwischen 5.8 und 6.5 sein und der ec wert nicht über 1.8 bis 2

It doesn't look to me to be a calmag deficiency.
Looks more like a phosphorus deficiency to me.
Could possibly be a Calcium toxicity also.
With a calcium toxicity they will be more prone to light/heat stress. Will cause phosphorus to fallout.
Can also make it look like there's deficiency in potassium, magnesium, iron, and manganese.
Soil may have alkaline conditions.

I forgot, now you should flush your plants to unlock her roots from all the nutrients stucked in your soil

hello mate, you did right giving CalMag but i think the problem is another. When you use organic nutrients you must have a Ca/Mg ratio of 3:1 or 4:1 in your water than you can add whatever you want because normally the brand products are already balanced. If you haven't the right ratio, normally you could have more Ca than Mg in the tap water, you can add Mg salts to balance the ratio.
Good luck and happy harvest!!

FLUSH, if you haven't already. Then get your soil right.
What "All_our_small_plants" said makes sense.

Not cal/mag issues, but starving for P and K.

Check runoff pH. Low rootzone pH is a common cause of Ca deficiency. High potassium can too. Ca also works with phosphorus, so bumping that might help with processing Ca. Too much isn't good either when it comes to CalMag.
