As the title suggests, I have a few yellow spots that popped up on the sugar leaves on 2 or 3 bud sites. I've done a ton of research, but can't quite figure out what the issue is or whether or not to be concerned. I'm in the 2nd half of flowering and some fan leaves/lower leaves are yellowing, but I understand that's fairly normal at this stage (within reason).
This is my first grow, but I've done alright with veggies and other plants before, so I'm not totally out of my element. Just figured someone here might be able to read the leaves a bit better than me.
In terms of the grow details, it's outdoor with 3 other plants in 5 gallon pots, all treated the same way, other than slightly differing quality of light due to placement. It's at about week 6 of flowering I think. Pistils showed up in force sometime around July 20th, in a zone 9 equivalent, so I counted from then. We're in the end of the wet season where I am, so temperatures have been ~23-26c in the day, lower and night, maybe 16-18c. I don't know humidity, but it's probably high with all the rain - not necessarily every day, but usually at least a downpour every other day.
Nutrient-wise, it was 5-5-5 organic fertilizer up until I saw the pistils, then I messed up and added the "wrong" nutes for 2 weeks... not the worst, but the NPK ratio on the bottle was 50-400-200, so higher in P than I intended. Of course this NPK rating can't be percent, but I think is measured in mg/liter, so I mixed ~18ml per 13L bucket (also used for fruiting/blooming veggies). I caught my mistake and switched to a 50-200-400 early in August.
Feeding schedule is every 7-10 days. Watering is every 2-3 days, but I check the soil an inch or 2 to see how dry and water it based on that. Some droopy leaves reminded me once or twice, but otherwise I try not to under/overwater.
The yellow spots are limited to only 3 buds or so and don't seem to appear other places suddenly, so I'm not super worried, but just want to have my bases covered.
I've attached pictures for reference, along with some of the healthier looking bud and rest of the plant. As a side note, I realize I introduced a bit of nutrient burn this week with those tips getting a bit crispy. Going to dial back the feeding by 50% next time to be safe.
Thanks in advance for the help and feedback!
