Here are some updated pics. It has been growing fast, and the new foliage seems very healthy and abundant. I believe the newest fans are 11 blades which I have heard to be a good thing. They seem to be uncurling slowly, so hopefully that keeps up.

Definately looks like humidity problem to me as well. Get an el cheapo humidity temp at wally world with a hi lo memory. I bet you will find that your running real high RH at night. The cure for this doesn't come in a bottle. Pay real close attention to your environment for a couple of days and correct the swings.

Cool, this is what I was thinking too. I bet that is the problem cause I truly believe all other aspects have been covered. Humidity is the only thing I am completely unable to monitor so its likely.

Should I get a humidifier to help with this problem?

All the ones I've ever seen do this was caused by over watering or either being root bound. Someone will more than likely say, "I've grown a 6ft tall plant in a 2 oz dixie cup, so root bound can't be an issue".....sure, but every plant is different. I had a plant that looked exactly like that, I tried everything you tried and nothing worked. I waited until the soil (which was MG, and it's perfectly o.k. to use to grow in, it's been done 1000's of times with no ill effects), was bone dry before watering, and still had the same issue, it confused the hell out of me. But once the plant was transplanted into a larger container with fresh soil and perlite, within a week the curling went completely away and took off. So, maybe wait a few days and see if it's still curling, and if so try transplanting it into a larger container, possibly a 2 to 3 gallon pot. If you're worried about "stressing" it, once you've transplanted water it with a little bit of superthrive in the water and that will help it rebound. Just remember to only use 1 drop per gallon of water.

Actually when it was a sprout, I ran into this problem. It became root bound, they curled, and a transplant fixed it. But I just transplanted it recently, so i'm thinking that's probably not the issue but I believe I found the problem! Got a temp/humidity gauge and found out that my humidity is between 20-24% with temps between 82-85 degrees. That must be the cause correct??

Those numbers don't seem all that bad. Most plants I've seen grow were outdoors, and when you think about it, in late summer when the temps stay in the mid to upper 80's and sometimes in the mid to upper 90's, and the plants never drooped; so I wouldn't think it's due to the temps. IMO I don't think humidity is all that of an important factor in growing. Yea, tropical plants are adapted to growing in high humidity environments, and plants that grow high up in the mountains are adapted to growing in very low humidity environments, but marijuana is neither a tropical or arid plant. It can survive, again IMO, in an environment that has a range of 20 to 50% humidity. I wouldn't go higher or lower than that though. I'll research some more on the humidity requirements for you. If the humidity drops lower than 20% try using a spray bottle and mist them from time to time. All low humidity means is that it will suck the moisture out of the plant, and soil faster than normal, so if you keep up on the moisture maintenance it shouldn't matter if you have low humidity. Just think of it as applying lotion to your hands in the winter time, lol.

Yea I didn't really think it looked too much a humidity or heat issue, but the leaves do feel dry and crisp in some spots. And another thing is that when I put it on my dresser by my window during the day, I cover them with a big clear plastic bin that is like a green house. It gets very humid and the plants def seem to perk up. When I put them back in the dry closet, they curl back. So I'm just not sure.

Are they uncurling all the way when you put the plastic bin over top of them in the window?

No not completely, but throughout the day they will get progressively better. Not waaay better but an improvement for sure.

humidity dont make leaves twist. low humidity will make the leaves feel rough. dry leathery. its not happy from food or ph as the tips are already clawing showing a deff. the old twsting wont fix itself
but it may be the humidity that is causing her to not process the foods right then it shows this as the reaction. that humidity is way to low. also stop moving from window to room. keep cosistant conditions

im never suprised by the shit people will say on this site....yea, you can grow in MG, just like yes, you can grow in low humidity...but your plant will not be as healthy as it can be....these are simple things you can do to improve growth/harvest weight, why you would grow in low humidity using miracle grow it unreal stupid to me!!....get that humidity up to atleast 60% until the later weeks in flower, then bring it back down to like 40% and keep the air circulating to prevent molds...

EVERY case is different but....... Humidity is WAY over rated.... I have excellent results with clones at 30% or lower humidity... Veg chamber below 30% often and flower chamber that was over 80% occassionally..

If you feed and water your plants regularly, humidity has JACK SHIT to do with how well your crop does... Dont stress so much at this point...Your plants look great... Just do what you have been doing and you should be fine... I have seen a lot worse than yours produce some nice smoke... Good luck

I used to freak out trying to keep my exhaust fans adjusted for proper speed, constantly checking Ph and TDS levels, adjusting humidifiers and dehumidifiers, checking runoff and so on and so on...... Its all rubbish.... Just water the damn things when they get thirsty, feed em when they get hungery, and smoke em when they get old.... Just like ya do with senior citizens

lol that is funny shit man that made me chuckle.

Nameless is acting like an new father. Worry, Worry, Worry . . . . IMO that won't help anything. Remember, it is just a weed. Change should be subtle. It is gardening 101 stuff. I like this thread 'cause it is a no-nonsense dialogue. grow 'em and smoke 'em! here is today's pic of my Afghan at day 12: photo #1 shows a healthy plant topped yesterday. photo #2 shows the pair living in harmony. photo #3 shows a close-up of the topped plant. There is a slight size difference, but they are healthy. I call 'em Arnold Schwartzenneger and Danny Devito from the film "twins"

i guess i need to remember some people are happy with anything at harvest time......

Environmental variables like RH and Temp play a hugh role in the health and development. If my RH stays at 80% for 24 hours, my leaves will start to look puffy and pale. This is going to be relative to how maximized your environment is. I'm sealed so 80% humidity only occurs if my dehumidifier isn't working.

That said, the "Just water the damn things when they get thirsty, feed em when they get hungery, and smoke em when they get old" crowd often get results that would make any grower proud. They invest less time, effort and money and often get the same results as the kitchen sink crowd.

humidity is way way important...to a real grow. yes they gropw in any conditions but there is a huge diff in yield and quality from the food not being processed right in to hi or low of humidity,....when i see people say it dont matter its cause they dont know how a plants sytem works...no offence

Just because certain soils COST more doesn't mean they are better. lol That is one of the funniest things I keep hearing. "Fox Farm this, Black Gold that", it's all a bunch of nonsense. If plants can grow, and grow great in regular outdoor soil then why can't they grow great in MG? The kind of soil doesn't really have much to do with it in the first place. If it did, then plants wouldn't be able to grow in just water. All the soil does for a plant is provide support and acts as a carrier for nutrients, that's it, nothing more nothing less, botany 101. Again, if soil played that big of a role then why can so many plants grow in so many different types of soils and have success. To say that you can't get as good results with MG as you can with FF or any other brand of soil is plain ignorant. As long as you give the plant the proper amounts of nutrients it needs to stay alive and give it an adequate growing environment then you can still have great results.

Weed plants can and do survive in just about every type of environment except extreme cold environments. They say the origins of Marijuana is the Hindu Kush region, and if I'm not mistaken that is a mountainous region, that is higher up in elevation, which again means it has low humidity. There is also alot of speculation that when weed is grown in lower humidity environments it produces more resin to help coat the leaves and protect it from drying out. Hmmmmm...just food for thought.
