After last question with those symptoms, I flushed her with pure 6.5pH water, then next time started to adding only Biobizz Fishmix, and another next time I started to add all nutrients again but 50% of recommended. Buds, the white ends of the flowers begin to turn brown as well.

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?

Saw this first day of 12/12
Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.

Bruising or nute problem?
I do not have enough characters here, please check diary for details. Some tops are showing some problems. The thing is, only a few and it does not seem related to light distance. My first thoughts is this is bruising, but I would like some more expert opinions.

I wanted to ask if you think this plant has mold or if it's just a major deficiency due to a blockage. I have an indoor plant next door with some plants growing with dark spots, it's in my previous question. Sorry for giving more information, I don't know what would help.

Dark purple areas on leaves — genes or environment/feeding problem?
What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐

Leaf tips are browning
Ciao tutti, What is going on with these leaf tips? It’s the third day of their Flush & It can’t be NutBurn, or the color of tips doesnt look like NutDef! Is the light stress? If this de-coloring continues, will it effect the buds & final yield? Thanks

Please check the last pictures I have posted. This is about a week after transplant, and the plant also has burnt tips. Are the brown spots from something other than transplanting into hot soil? They are in KIS water only soil and I have only been giving well water, ph is 6.8ish
