im having big problems with this single plant. the leaves are curling inwards and getting stiff. this plant has been the only one doing it and ive done a flush like 2 weeks ago. the leaves been like that for a few weeks now and only is getting worse. ive also seen it in another one of my plants but the other plant seems like its getting back to normal while this one is still doing it. ive been checking the ph in my water and soil as best as i can till my meter shows up in the mail but dont know why this is doing this so badly. they were doing pretty great up till now. any suggestions would be greatly apreciated.. thanks guys

Are you foliar feeding?? Is there a hard breeze going across your leaves?? Looks like maybe wind burn.

[cigarettes42]

A strong wind could do that? Actually I do have kinda a strong breeze on it. I have a box fan on low and proped up kinda high on boxes but is still kinda strong on the tops. Thanks btw!

I've kept a strong breeze on my ladies for years, never seen results like that. Especially on just one plant in the grow.
Do you foliar-feed?

[cigarettes42]

once in a while I folier feed with a highly diluted solution of foxfarm nutes

[Rusty Trichome]

Only other thing I can think of, is major ph fluctuation.

[stinkyattic]

Looks either pot-bound, suffocated, or over fertilized. All 3 can lead to the downwadrd cupping you see on those leaves.
When you answer rate of application you need to be more specific. How MUCH do you use compared tot he instructions on the bottle?
You're probably going to need to flush with pH 6.7 water, repot, and feed lightly with your grow big.

ive been very light on the ferts. do you think its from when i sprayed em with milk? cause after i sprayed with milk its doing this. i sprayed water on the leaves to get the milk off but didnt get all of it off i dont think. my other plants that ive sprayed with milk are also getting brown spots on em. but those plants seem to do fine. also do you think its cause when i had em in styrofoam cup i transplanted in 5 gallon pots right away? i heard that its bad cause you cant accurately monitor the watering and ferts and such? thanks stinky!

Woah wait - who or what told you to spray your plants with milk?

[cigarettes42]

i got a home remedy for killing mold. bad idea from someone. my leaves instantly canoed upwards in like an hour. i sprayed em down with water to wash em off. bad idea but thought it would be ok since there was a link to this being done to plants, not mj. lesson learned. i got serenade and fixed the problem. but now my plants smell really bad from it but now the smell is starting to subside

[Rusty Trichome]

Shit. Milkbaths would have been my next guess, lol. (kidding)
You really sprayed them with milk? Wow.

Give 'em calcium in a form they can uptake. Plenty of nutes and additives out there that do the job right, when a deficiency is spotted.

[cigarettes42]

quit bustin my balls! haha, ya i did give it a slight milk bath. actually i deserve all yall bustin my balls for doing that. lmao

[chongman420]

Was it skim milk? Or 2%? And did you give them some cookies to go along with it? Plenty of calcium and vitamin D :S2::S2::S2:

[cigarettes42]

it was whole milk. i was trying to give my babies a milk bath. its good for their complexion and its suppose to be rejuvenating. any stessed lady needs to be pampered once in a while. i also was going to give her roots a hotwater salt rub and give her a mud mask but i got lazy.....
