Deficiencies while in late flowering during flushing period
There is deficiency going on (looks like cal) she is an auto flowering strain in her 9th week and been flushed for a week now. Should I give her cal/mag and stop the flushing or is it too late to deal with that? She looks like she will be ready to chop in a week or so.

Whats wrong with her?
I cant tell what's wrong with her. I recently upped my CalMag nutrients cause I originally thought this was a Calcium deficiency (full nutrient breakdown in diary). I dont want to hinder my harvest so any insight?

Calcium deficiency?
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?

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.

Brown dying leaves
What is going on with my leaves? Even the sugar leaves are starting to die. Sprayed with optic foliar switch to prevent male flowers popping up a few weeks ago so could be that.

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.

Orange spots on fan leaves
What are these spots due to? I was using pH 6.5 tap water and bud candy 1mL per L for every watering. Just water from now on. Should I worry? 2 weeks left before harvest
