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.

The brown spot problem is still the same. I reduced the fertilizers to 1/2 dose according to the week after 1 week of just bottled water. The pH of the solution is generally 6.3-6.5. Apparently, the central cola is thicker, but I find it hard to notice the difference.

Deficiency/Light Stress Issues
What else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

leafs with brown spots and olders become yellow and curled
I'm trying to figure out what is the problem with the growing of my plant. The upper leafs are quite normal, even if they tend to bend downwards. The old leafs start with brown spots and then they become yellow and curled on the peaks. Please help me to understand what's going on

The last few days I had 3 plants start not looking so hot. The 3 pictures are the 3 plants when I got home today. I haven't really encountered deficiencies, if it's even that. I'm watering at 5.8 and last I checked the runoff a 2 days ago it was 6.8. Any ideas?

Leaves turn brown all of a sudden
What could these brown parts mean? They show up randomly, also on lower leaves, so couldn’t be the light being too close? Thanks!

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?

Hey, on my biggest plant, the leaves are starting to turn yellow from the outside and getting brown spots. Is that a sign of over-fertilization? All the other plants don't have this. Or is it too little?

The leaves of my plants have started to have spots, I've been told to spray them with potassium soap and neem oil at night, but it's getting worse each time. Could it be a lack of nutrients? Some fungus? Or leaf burns from potassium?
