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

Hey guys I'm puzzled i took one picture of a leave from my Royal Ak 47 Auto. As you can see this is not a nice green healthy leaf (many others are like this). What's the issue? Is it worth treatinbg this late in the growing stage? Love to hear your opinion :). Cedji

Brown leaves - what am I doing wrong, folks?
They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

I'll just leave this here.
Only a few leaves, but should I be worried? Last few waters have only had calmag to see if that helps.

Plants deteriorating rapidly, pls help
Plants not looking good! Help! White tips at the end. Brown patches. Leaves curling. I've been feeding it 0.5L Advanced Nutrients Coco Big Buds. The light was fairly close, at 30cm. I've raised the lights to 60cm. It was also very humid, so I've opened the air vents .

Do I have too many leaves? Should I have been more ruthless in the early weeks of the flowering stage? I also have variegation on one of the plants, is this a disease or deficiency? The plant seems healthy enough though

What is causing this?
What is causing this? It only seems to be on the older leaves and only on this plant. They’re all being fed the exact same.

About the 3rd, 5th and 6th picture. What's that? I always assumed it was P deficiency but I got P def on another plant and it doesn't look like that. I've had the same stuff on multiple plants. Also about the 4th picture, bottom leaves drying and white-ish between veins

Nutrient Deficiency
Is this a PH issue showing or nutrient deficiencies (possibly caused by bad PH anyway, at 6.2 atm higher from earlier in week.)? Possibly magnesium deficiency, looking at pics. Anyone confident? Been hot in tents as well but water temps kept decent about 68-70.

I have some kind of deficiency but not sure what. I’ve flushed & hit her with some cal mag. It’s almost time to flush anyway, (day 45) is there more that I could do? She’s got some buds, maybe fine 🤷♂️
