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

White-spotted leaves, any deficiencies ?

Calcium or Phosphorus Deficiency?
One of my 3 Cream & Cheese has upper leaves on 3 stems/colas per the pic. The lower leaves are OK, the other 2 plants are fine. Thought calcium at first as phosphorus is more lower leaves? Maybe just add CalMag? Thank you so much!!

Yellow mottled leaves with burnt edges
Help. After months of babysitting my "autoflowering dwarf" it's finally started flowering. In the last week though all the leaves have become mottled and yellow with burnt brown edges. What can I do to save her?

Brown/rust spots have been increasing on one of my 3 plants. Appearing on upper and lower, newer and older leaves. Does not appear to be a light/heat issue. Treating it as possible Cal def by increasing cal-mag nutes.

Does the paleness concern you?
Plant #1 seems a bit more on the pale green/yellowing side of the spectrum. Especially compared to plant #2. I have been feeding this week on a gradually increasing schedule. Not enough characters to go into it here.

Sick plant, could be temp, nutes, too much water?
Leaf tips looking burnt and wilting in flower ... keeps getting worse no matter what. pH 6.8. Raised light. Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same. I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Leaf discoloration... having a hard time deciphering it.
Starting to see some leaf discoloration, possibly some spotting, and most recently noticing the tips of newer leaves looking a little burnt. Any experience growers want to point me in the right direction? Seems like it could be nute burn, or potassium deficiency?😩

Bright green spots and wilting.
I seem to have some wilting with some bright green spots on some leaves. I just potted up and she's at 20DLI, 0.6 VPD, 790EC @ 6.0pH. 75F, 71%RH, autoflower in canna coco pro plus.I turned my fans down a little since they were a little aggressive, so I'm hoping that's the issue.
