Browning on the leaves?
I am worried about the leaf colour I feel like it’s slightly browned on the tips. Interested on what others that know what they’re looking at more than me think. Good chance I’m being over protective. I appreciate you.

Weed doctors to the rescue
Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

Brown Rusty Dots
What are these brown dots on my plants? They are only on one of the plants, they have gotten a spray with Dr. Zymes Eliminator and had no effect, also did a mL of Cal Mag in its last water with no effect and getting worse. I’m not sure what this is and I can’t get it to go away!

What is causing this on the leaves? I'm not sure what I am doing wrong. Is it possible the heat and humidity are too high? Humidity up to 77% and can't seem to get her down sometimes. Heat is around 27/30 degrees during light hrs. Did I fuck up the transplant or grow conditions?

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.
