Calcium deficiency?

GreenCosmosstarted grow question 2y ago

Saw this little brown/yellow parts today. She is in BioBizz LightMix Soil and gets 0.3ml/L BioBizz CalMag 3x per week. pH is above 6.5 . Today I gave her 1ml/L CalMag. Was this the right choice? Is this a calcium deficiency?

This is calcium deficiency and likely due to ph getting too high. Likely need to increase feed amounts

I'm not sure if it's calcium because it forms from the edges and makes lines, which seems more like PHFluctuations

PH measuring for Organic Growers If I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.

What am I looking at?Redish Brown spots, and slight discoloration. Magnesium deficiency? Calcium? Other? Gave them a splash of Calmag, but was it even necessary? OR, should I have just swapped nutes and wait, then correct if not improved? (It was nute day, that's why I ask!)
