This look like rust fungus. More ventilation, lower humidity levels, remove all infected leaves and get them out of there and burn them. Maybe do a little research. Could also just be magnesium or calcium deficiency or lock out. Cheers

Looks like spider mite infestation. Look under the leaves.

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

Discoloration bud leaves
Anybody know what this discoloration is? Humidity was a bit too high so I'm hoping not some type of mold. The affected buds did get quite a lot of wind and light, so it might be light- or windburn? Any help appreciated!

Brown spots new leaves - flowering
Brown spots on the canopy and leaves are less greener. I suspect it is Calcium deficiency caused by a acid Ph (my Ph meter was not calibrated). I have flushed it and fed it normally 5 days after the first signals. Is it really Calcium def or another thing I'm missing?

Was hat meine Pflanze?
My Lemon Cherry Cookies has had brown spots on the leaves for a while now. I'm fertilizing according to the BioBizz schedule with half Grow since it's already flowering. I also add 1ml/L of CalMag with every watering, check the diary.

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

I am seeing an issue with the lower fan leaves and it seems to be progressing upwards. The leaves are yellowing and also seem to be turning brownish. I added CalMag into my last feeding but beyond that not sure what I should consider, info/advice is appreciated. See last pic wk5.

Possible manganese deficiency?
I fixed some previous issues and have not been feeding my plants. They are in peat and worm castings and pearlite. About 6.6ph soil, watering with 6.5-6.6 water. I am going to water with nutrients again to see if that helps just want to hear another opinion.

What is this brown intrusion upon my plant? And how do I obliterate it?
Another question?! Anyway, what the hell is this browning? I think it's light burn. But why is it lower too? PH? Magnesium? Nitrogen toxicity? Par: 1300 PPFD Fox Farm tiger bloom 7 ml/gal. Fish Shit 3 ml/gal. See diary for environmental conditions. Thanks for the help. Again.

brown spots on older leaves
The brown spots are appearing more prominently on the older leaves. Overall, the color of the leaves is rather light green compared to other grow diaries. What could I do to fix the deficiency?

Brown dark spots on fan leaf
Any clue what this is? It only appeared on 1 of the plants and only on 1 of the fan leaves. The brown color has kind of a metallic shine to it. My guess is that it’s a Cal. def. I also suspect it might be a Phosphorus def. as the plants turned dark green the last few days.

Please say it ain't bud mold :(
Noticed a brown spot on my center cola last night. This morning it progressed so I removed it. I'm noticing browning on nearby leaves. It may be nute burn (I have been heavy on them), and I did recently increase light intensity to full two days ago, but my temps are ~74f. Pls no!
