AsNoriuanswered grow question 1d ago Omg !!! One calls ph 6.5 acidic and low in soil, other dont understand anything about nutrients and how can they be delivered to plant.
Calcium nitrate, epsom salt and if both needed, then its easier to use CalMag.
In soil grows calcium is almost no needed (same as silica not needed in soil grows) , its abundant in soil or water ....
That platform should review this section, its going beyond absurd ...
