Not sure why but I'm guessing your pH was a little high 2 weeks before this. Ok did I bingo?

sure ill play along, this looks like too much nitrogen at some point or this plant is a very picky eater, either way less nitrogen

Cat piss? Not the strain....
So I've been having these brown spots, thinking bugs or aphids or.... but I spotted a neighborhood cat around our yard today, marking its territory elsewhere on the yard. Could this be cat piss sprayed on the leaves?? I wouldn't put it past this fella.... but not sure. Thoughts?

I'd like to know what happened to my plant but I'm unsure how to properly describe it. The photos in my diary should be able to make it more clean (W18). Maybe it was botrytis but I caught it on time? Or maybe something else? The trichomes got dark orange where all this happened!

Plant #1 is showing some leaf discolouration. Not sure if it is nutrient burn/lockout or deficiency. I flushed her with R.O water just in case. Any ideas or suggestions? She's an odd one anyway, seems to be a different phenotype than her sisters.

Getting weird brown growth at the base of the leaves on new growth... anyone know what this is and how to treat? I may add I have no signs of any pests , bugs or anything. This is a full organic grow therefore I did hit it with essential oils as a pest prevent a week ago.

Something ate a hole in a leaf last night. It not a complete hole through just the chrolophyll was scraped off, leaving a yellow bite mark (picture in diary). I removed a caterpillar looking thing from my tent this morning, no idea how it got there. Could that have been it?

Is this Yellow spot septoria?
Hi gromies. Is this yellowing caused by septoria? Or just normal N deficiency during flower. I can see minor pest remains ob leaves and stuff but not affecting plant overall. Plant in good air flow and humidity around 50% so I question whether it's septoria. thx in adv.

Little browinish/beige dots near leaf veins
I noticed some weird little browinish/beige dots near the veins of some leaves, mostly the upper/center ones, those exposed to the light. I checked for bugs everywhere, even with the jewel loupe, and I haven't see one. What can it be? Maybe heat/light stress?
