Salts building in your planter, causes lockout. Ph out of whack also causes lockout. Check both.

Would Epsom salt be helpful for these brown spots? If so, how many ppm? Is it OK to reduce pH with citric acid and distilled water in nute mix?

Rusty brown spotting on upper fan leaves, too much Tiger Bloom or deficiency?
Hindu auto, week 11 started seeing rusty brown spotting on upper fan leaves. At this point I was only using tap water and 4 tsp/gal of tiger bloom. That is aggressive so I backed off to 1.5 tsp. I watered with cal mag 1 tsp just in case it was deficient. Ideas? Buds seem ok.

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!

Burnt? PH lock-out? too much Cal-mag??
What do you think is wrong with this plant? All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

Is this bud rot?
I found strange purple/dark brow discoloration on one of buds and surrounding leaves. It could be caused by bad supercropp of the cola, or I am thinking bud rot. What do you think, should I harvest immediately, or am I stressing too much? RH is 50-60%, but the box is cramped.

Maui Waui CA deficiency?
Can anyone confirm or guess at the kind of deficiency my plant is having? I am not sure if "hard water" (instead of RO so far) is the right answer or if I need some special sauce... Thank you! Details here: https://growdiaries.com/diaries/139533-grow-journal-by-fejg87fb2skvf

Flushing don't seem to solve my lockout
It's been 6 days since I noticed the problem. first thought it was a deficiency but really is a lockout. I flushed 2 days ago but she keeps getting worse. Am I being impatient? I flushed with tap water pH 6-7 until the runoff was in the same range and haven't fed her for 4 day.

1. Over Fed (seaweed?) 2. Burnt? Cauliflower.. 3. Calcium Deficiency 4. Hydrogen peroxide 12% Food-grade 30/70 Mix. Personally I think it's the hydrogen peroxide 12% mix, the hydrogen gave one of its atoms to the neuron of the Diatomaceous earth metal clay. With help from heat
