Calcium deficiency?
Calcium deficiency?
GreenCosmos
started grow question 7 months 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

What’s wrong with my plant?
I’m need to flip to flower soon but hoping to figure out this issue or deficiency. Any ideas on how to cure the leaves yellowing and browning? Not sure is this is Septoria or a calcium deficiency? Any help would be appreciated! Thanks

Should I be adding Cal Mag or is Flora Nova bloom sufficient?
Guy at the hydro store recommended GH Flora Nova bloom. Started week 5 with it. Should I be supplementing it with Cal Mag at this point? Some in it already.
