Hi, Worrying this might be something else other than some nute burn...? Only on some of the leaves of one of my 5 girls. Any opinions? Thank you

Looks like possibly some wind burned tips from being close to that fan. Or from rubbing on your tent sides? Or just some nutrient burn. I'd not worry about it much unless it's happening to new growth. 🤘😤

To me looks like nutrient burn are you checking PPM of the run off water?

Yellow and fragile leaves 2 week Couple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn. For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.

* Spots (pic 4), on only 3 leaves of the plant at the top. Last week, before lights out, I misted. By lights-on time, some parts of the plant were still wet. Is this some water burn? Tap water is PHd and ~215 ppm (plenty ca/mg) * Any insight on those yellow tips is welcome! :)

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)Ich habe 2 Pflanzen in Zelt und eine der Pflanze zeigt ziemliche Mängel. Viele Blätter sind mittlerweile gelb mit braunen Flecken. Die andere Pflanze hat diese Mängel aber nicht, beide wurden gleich gegossen, etc. Ich habe vor ein paar Tagen DolomitKalk und Worm Casting benutzt.

Bottom leaf turned yellow with brown on edge Hello this is my first grow and had noticed a leaf turned yellow with brown spot on the edge. This is a northern light auto just kicking off with her flowering. I use advanced nutrients 3 in 1 micro grow and bloom and that's all I've ever used. I suspect a nitrogen deficiency...?

Yellowing, burnt tips and edges Hello fellow growers I noticed this happening rapidly after I top dressed. What kind of deficiency is this? Is this nutrient burn as well as a deficiency? Solely a Ph problem?. So far I’ve come up with maybe potassium deficiency and improper Ph when watering? Please help

Did I do the right thing? Pls check my update on this week!Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

What to do? Leaves are getting worse.Had some light strain earlier on, but now im leaning toward a deficiency. Been feeding on a low-dose flora series schedule with clean ph water for every other feed. Just had clean water yesterday and nutes 3 days before. Dry out between feeds. Nitrogen? Calmag? Other?

Leaf tips browned. What nutrient problem is this?Leaf tips browned. And some signs of burn/discoloration at the leaf side edges. Do you think it's general nutrients overdose? I didn't increase my PPM for the last two weeks, so I don't think it is a problem... Or Potassium deficit? Or any other secondary nutrient deficit?

Harvesting a struggling plant or just letting it fight Can she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me. Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.
