Brown spots
Benasquellastarted grow question 4y ago
Hello team! I've got brown spots on my leaves. I've used my microscope and can't see bugs. I've been feeding about half neuts (2.5ml/L canna vega) ph is 6.5. In soil. Can't think of anything I've done.

I had a look at your diary. I'd say this might be a air circulation issue or water sitting on the leaves after watering, or leaves touching the soil. It looks like a disease more than a nutrient deficiency. Is it isolated on the lower leaves? or is it evenly distributed through the plant? I'd say its some kind of rot and I'd clip the infected leaves off and monitor to see if it spreads. If it does then it could be a soil borne disease or nutrient issue. If it doesn't then problem solved.

I think you potentially have a calcium deficiency. Try adding a little more cal mag on your next feed. Good luck bro 💪

I flushed it because some leaves were showing some Nitrogen Toxicity. Run off was coming at 3000ppm and I fixed it to 1500. Now the older fan leaves are yellowing with some brown spots (check the last picture). It's a deficiency? Should I increase nutes? Thank you very much!Week 8

Rusty Leaves3 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 spots sugar leavesI've asked this before, but the issue still seems to be there though it's very minor. Some of my more developed buds sugar leaves are showing brown markings. Last watering I flushed her but the markings seem to be spreading still, although very slowly. What am I dealing with?

What do you think is causing the spotting, leaf curling, and stunted growth in plant #1? My money is on light burn and/or PH issue. I have a PH control kit I've been using to treat the water, but do you think just treating the water is enough? Using FoxFarm HF soil, no nutes yetWeek 2

Brown spots/yellow tips after accidentally breaking a bladeHi!
I accidentally broke an older blade from one of her leaves, and after a couple of days that leaf started getting brownish spots and slightly yellowing tips.
Is this normal to happen after a broken blade and will eventually die off? Or is this any sort of deficiency?
Thanks !

Browning leavesMy leaves are showing some brown spots 5 days post transplant. I also increased my light from 30% intensity to 80% intensity. I have them 18” away currently. Am I showing signs of light burn? I have since turned the light back down to 50% and I am not on a 18/6 cycle

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared.
Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.
