Tips curling down, not the leaves

[growmie]

Any ideas as to why just the leaf tips are pointing down on this plant? Leaves aren't drooping, just the tips. The other plant which is a different strain isn't doing it. Thanks.

I'm in organic soil. 25% top is happy frog, the rest is ocean forest. I don't add fertilizer. Do you think the plant has hit the ocean forest and it's not handling the nitrogen well? Or could it be watering often, like wet wilt, but if it was an over watering issue the whole leaf would be drooping, no? .. or could the oscillating fan be the culprit? It's not blowing directly on the leaves. Weird.

The curling sure looks like excess nitrogen. Does or did it happen after watering? Sometimes watering can result in more nutrients being available to the plant.

Yes, I did notice after the last watering. It's definitely Nitrogen toxicity. I'm pissed. I was told ocean forest is too hot for seedlings but good for veg, and will dilute before the auto goes into full flowering.

I want to save the plant. I don't think flushing would help any, because it's the soil itself that has the excess nitro. I don't add fertilizer.

I'm wondering if I should give water with Mycorrhizae. Aka, "Recharge" so it may protect the roots from this toxicity?? But then again, doesn't Mycorrhizae help the root system uptake more nutrients from the soil?

Bah. I'm pissed. What are my opinions?

I hear if you add sawdust as a top dressing it should reduce the nitrogen in the soil.

There's a good chance the plant could outgrow it. I would probably let the soil dry well between waterings. As the plant gets bigger, it will consume much of that nitrogen. A light flush could help, but other nutrients are removed along with the nitrogen, which can cause other problems.

Recharge might help. It's worth a try. The mycorrhiza should help.

I don't know about using sawdust. I wouldn't use any that was from composites or plywood that use glue or inorganic substances.

mild nitrogen/lockout - plain pH'd water, until they start to respond (next 2-3 waterings) they'll snap out of it. Ocean Forest is fine for Auto's, its only Hot for seed starts/seedlings
what type of wood/saw dust? I dont recommend this idea.


nothing grows under a pine tree for a reason... pine sap is how we make solvents, pine sol, turpentine...etc
many milled woods are treated. KDTA Kiln dried treated arsenic....

careful now...

@Choppr I won't use the sawdust method although it does work. The sawdust needs to be composted. Fresh sawdust - or any fresh wood - saps the nitrogen from the soil as it decomposes. The wood /sawdust would be natural, from (peach/cherry/apple/mango) trees, and not pressure treated lumber or sappy woods like pines, spruces. Bone meal is another indirect solution to dealing with high nitrogen levels. Wood chips and Straw are also options.

I'll let them work themselves out I guess. Nothing I can do. The soil is hot regardless of stage, cause I'm in pre-flower and I'm seeing nitro toxicity. Shouldn't be that way.

I'll also keep my eyes on the pistils to see if they die off or continue to grow out in a positive way.

I suspect a slight watering issue and a nitrogen issue but neither is really concerning. Notice how the leaf edges curl under giving the leaf a concave, puffed up look to it? They are holding a lot of water. A little extra dry time and touch less water should fix that. Your plant should grow into the soil quickly and a little bit high N shouldn't be a problem. My plants often start out like that and they do fine. Some strains are more prone to clawing than others, I've found.

I agree that it's important to know about sourcing if you plan to use arbor fines or sawdust. Personally not a fan of sawdust but I do use locally sourced arbor fines that come from both logging and planned clearing by the forestry depth to help manage wildfire threats. It's all wild harvested and untreated. Fir/pine tree products have low pH similar to peat moss so keep that in mind. I like it because I can use less peat moss. It's kinda multipurpose. Both water retention AND pore space in one. It has a reasonable CEC and it's a great habitat for microbes.
