Have burnt hairs on my buds and tacoing new growth.

[ericf8754]

Hey there guys I have some white hairs on my buds starting to look burnt. Not to sure why I know it's not to hot or the lights are not to close. I also have taking happening on my new growth with the leaves curling inward and down. I have a couple pics below any help would be greatly appreciated.

Nice plants.
The hairs will go red/ burnt naturally as the plant matures.
Have you changed how you water?
Drooping is usually a water issue[ too much usually].

Others will be along to help more.
They will want to know more like grow media, lighting and details ,ferts, RH[day /night] and temps [ day/night].
How many weeks into flower are you?

Don't know if this is applicable in this instance, but some insecticide or mold sprays can turn pistils prematurely dark.

The new leaves are cupping because the amount of salt in the soil is greater than in the plant. Water always follows salt and if the amount of salt is greater than in the plant the soil will suck the water back causing bear claw or cupping.

You may want to use water only for a few waterings to lower the amount of built-up salts.

OK thank you very much I will try that out.

I'm concur with steam roller that the oldest stigma will mature and go dark naturally. And yes. It sort of hurts because some strains keep their white stigma longer. But if haven't sprayed anythjng on them probably normal.

Hey man thanks for the help I have only grew one time before and new it's legal in New York so I figured I would have a go at it again. I use Happy frog potting soil from fox farm they are in 7 gal fabric pots, also fox farm nuts, I keep the humidity between 45 and 55 and the temps between 78 f during the day tops 66 f at night for a low humidity normally stays right around 50 percent in the tent. I have the ac infinity people system that keeps the temp and humidity were I want them. So really I thinks it's just to much or to little water and or nuts both put together. I water them every two to 3 days depending on the moisture level in the soil. I just recently started ph balancing my water. I think this might also be the problem as the nuts stored in the soil are now all going to the plant with the correct pH? That's my guess after talking to a few people on these forums.

If you are ocd on temps and rh check out the vpd chart.

 

[ericf8754]

Is this vpd chart on this site also? Or just any chart online. I have looked into this briefly before but I don't know much about it.

No, that's boron deficiency. Looks like that when it's caused by bad humidity. When you see burnt hairs with it, it means a fan leaf was sitting on the site for a while, rubbing the hairs and raising humidity around the cupped leaves.

Nice I am NY [Saratoga ] and Fox Farms also!.
I skip the Tiger bloom and go with their dry 3 for flower.
Might like it 80-82 during day.
VPD will help you set temp and RH to help the plant the most.
You'll need a infared heat device to get it dialed in .
I like my inkbird.

I use this chart as it can be adjusted to match difference in leaf surface temp.

Oh OK gotcha I can't seem to get it hotter in there unless I turn the fan off that blows in air from the house. I feel like it will get stale in there if I close the vent. Maybe I can just turn the fan off and leave the vent open..... I will try that for a day and see what happens. Appreciate the help man.

That's the same as what I have for my current grow, except I have one plant in a five-gallon pot. I also have an ACI controller and fans.

I have had the same tacoing problem with the plant in the smaller pot. I forgot to mix in anything (like perlite, for example) for drainage, so the soil has been too moist, which can cause nutrient lockout. The solution has been to let the soil dry. I use a moisture meter to test the moisture level deep in the pot--about 3/4 of the way down. The plants like it when it's very dry down there.
