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

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

Healthy?
Sie wachsen zur Zeit sehr schnell allerdings haben manche Blätter Flecken wie man sehen kann. Die ersten Wochen habe ich leider mit einem zu hohen Ph Wert gegossen (ca 8) dies habe ich jetzt aber angepasst und sie bekommen ihre 6,4.Vielleicht Nährstoffmangel? Bio Grow hinzufügen?

Today my plants got something weird on their leaves. Some stains appeared on older leaves, and the new ones have a strange color, it looks like they are painted. More or less the same on another plant, some edges on new leaves look burned and weird color and shape on new leaves

Weird Spots on almost every leaf overnight? (Leaf Burn???) My plant developed these spots on the leaves basically overnight...
I was looking after them just yesterday evening and the plant was fine, however I did a mistake. The left plant got completely wet (i had to move it through the rain) and i did not dry it before the light went back on. Right plant is completely fine. No pests (thrips spimis etc.)

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?

What could this be? Deficiency, or pests?
White Crack in coco, currently late veg / pre-flower stage. Canna nutes being fed at EC 1.7 / pH 6.0 with runoff EC 1.3 / pH at 6.2. Noticed this on a single leaf this morning. Only change in last few days is that I am now filtering my water before mixing in nutes. Any thoughts?

There is a little bit of minor yellowing/browning in spots, on a few fan and sugar leafs. The plants otherwise seem healthy. Is this a normal part of this stage of flowering, or should I be concerned about nutrient issues? Thanks!

Brown spotting?
Hey everyone! My plant is in her 5th week and a few days ago (around day 30) I noticed some brown spotting on a few of the mid/lower leaves. Does anyone know what this could mean? I gave her her first feeding 3 days ago. 1/4 strength veg nutes and 1/8 strength bloom nutes.

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.

Recurring Cal Mag issues
I’m already at the maximum recommended cal mag dose of 1ml/litre (with nutes at 1000ppm or E.C. 2.0) and I’m still facing issues. It went away for a few days, but it’s now back. Should increase the cal mag dose and cut back on the macro nutes to maintain 1000ppm?

Hi there, does anyone have any idea what the slight mottling is on the leaves of two of my plants. There are close-up pictures under Day 27 in Week 4. The discolouration is present across multiple leaves, but seems to only be happening to two plants out of 8. Thanks!
