Brown tips, curling leaves

FXRocketstarted grow question 4 years ago

Some smaller leaves and top leaves have brown tips. Some are curling up. Is it too much fertilizer?

Nut burn, dial back for a second.. if you have an EC mater than can help, but don't expect the reading to be accurate in any way. (similar to why lux doesn't tell you anything about PAR on its own.. it's a poor measuring stick for measuring amount of dissolved solutes, even so, if it is extremely high or low it is a good indicator.) get pH in order, get TDS in line.. should improve quickly.. .don't let it progress... I have the same thing with some vege crop - ggxww you can see it in my diary. I overfed.. need to give pH-only for a bit.

Looks like light burn / heat stress try backing up your lights some. The curl makes me think so! Happy Growing! 👊

Praying leaves The leaves are stretching up (praying leaves as I understand). It's just 1 day after topping and I would expect some stress, is this a good or bad sign? I fear I might have topped them a bit too early.

Curling new growth All of my new growth is curling a little bit. I dont think it's N toxicity, but it's also probably not heat because all of them look like this. Is it N toxicity or something else? Thankss

They all seem good now

More rusty spots See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

Rusty Leaves 3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??

Necrotic spots The last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!

Two part leaf question.Two parter 😁. Are the new leaves on my plant deformed or am I being paranoid? How can I stop leaf curl? At first I thought it was a light/heat issue but both light and temps are fine and it doesn't feel too humid in there. See more pictures in my diary.

browning leaves Anybody have any idea on the cause of my leaves getting brown spots and curling at the tips? It's really just on the big mature leaves and leaves near the buds. Any smaller and younger leaves are still fine. Maybe a nutrient issue? Or is it just that its close to harvest time?

Light Stress Had to move my plants to a new space and under a better light, can see taco type appearance to leaves, I'm assuming this is due to light stress? I've lowered the plants and also turned the light down a little until I know what is going on.

Help with burned leaf tips The tips of some of the leaves have begun to dry, curl, and look to be dying (see pics). I think it's some sort of nutrient burn, but I'm unsure. I water every other day w/ a solution of Miracle-Gro 24-8-16 at 50% recommended concentration. Used distilled H2O last 2 waterings.
