if i use pure calcium, should i add calmag?
I’m sorry I missed that you were adding that calcium. That could be your issue. To much of that can lock your plant out.if i use pure calcium, should i add calmag?
just increase the epsom salt, at the moment it gives 1g/gal then maybe try 1.6g/gal? ThxThat's a magnesium deficiency, not a calcium deficiency.
But could be caused by too much calcium and magnesium is locking out. I would ditch the calcium and epsom at next reservoir change and use a commercial calmag solution. To easy to get things out of whack in hydro when mixing your own brew.That's a magnesium deficiency, not a calcium deficiency.
Yes 15.5-0-0 3g/galIs that calcium nitrate your adding?
