Anybody know why I’m seeing brown spots and burnt tips? I think it might just be time for a res change. Haven’t done it since I flipped and she’s been drinking about 1.5 gallons a day for the last 2 weeks.

Burned upper leaf edges
Hi! Dark spots appeared on some upper leaves overnight. I don't think this is the cause, but I did a pretty heavy defoliation the day before. the spots only affects leaf margins and makes the tips curl up. The spots are brown, burned and slightly purplish. what could this be?

I already posted it, but it's better to see here and it continues to spread
This appeared after a strong storm, but it doesn't stop spreading..two guys told me it's from the wind, as I assumed, but with the fact that it's spreading further, I'm worried

My plants are suffering a Phosphorus deficiancy due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. what should I do? I went to check on them today and the amount of damage they took in 24 hours was bad.

Brown rust spots on oldest leaves
Brown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?
