Calcium deficiency?
GreenCosmos
started grow question 3y 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

Rusty Leaves
3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.

Emerging Issues - Week 9
At the beginning of the week, I noticed the tips of the leaves drying out. Now, one out of the four plants has completely yellow leaves. Could it be due to the increased Biobizz Bloom dosage? For more information, please check my journal. Regards.

Continuing calmag deficiency
What I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated

Deficiency?? Excess? Neither?
Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.

Are those nutrient defficiencies? Which ones?
A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).
