Hi @blendmedmedman! This looks like pH fluctuations to me. You should buffer your pH to ~6.2 which is the sweetspot for regular soil. Watering with the wrong pH will slow down or block nutrient intakes, leading to a slow growth / poor health of the plant. Get yourself a pH-pen, these aren't expensive but definitely helpful to get a successful yield. By the way, you should also buy an EC-meter, this will help you to manage nutrients and adjust your feedings to the plant's needs. Hope this will help, let me know in the comments section if you need further information. Happy growing! 👊

What are your ppms? If you're running 5 tsp of beastie blooms you may be over feeding. Beastie blooms is a super concentrated bloom nutrient, I'd start at 1tsp of Beastie Blooms and build up from there until you're comfortable. I know my last grow I was feeding the equivalent of 2tsp of beastie Blooms, 2 times a week.

If possible measure the drain for pH and EC, may be overfeededor a lockout caused by wrong pH.

Fan leaves curling up could be either high temps or nutrients burnt. Slight over fert to me so correct you feeding dosage. Be careful of the Male, the pollen sacks can open from a day to another and the pollen is light enough to travel far.

I think it looks like overfert or lock out. When the plant is given to much of one nutrients at any one time, it creates a lock out. Ph level of water needs to be analysed as too high or too low can make it hard for plants to absorb certain nutrients, just give her a couple of weeks plain watering until she looks healthier. 🌱💦Should recover

More rusty spotsSee 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.4 years ago

Rusty Leaves3 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??

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.

Necrotic spotsThe 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!

Light StressHad 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.

browning leavesAnybody 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?

Help with burned leaf tipsThe 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.

Runtz muffin curling leaf updateI posted a question yesterday regarding leaves curling up on my 10 day runtz muffin, presumed heat damage but after a feed and 24 hrs she's come back from it, recently upped the light to 400w, do you think they just take a bit of time to adjust to it? They all seem good now
