Not sure this is the right place for your post - may get batter results starting a new thread. Provide more info: What strain, what type of medium, what has been added to the medium (nutes? supplements? etc). How we is the medium, etc.
Gl man!

one of my grow boxes which is roughly 1.5 square feet with about a 150W cfl setup, sits at about 26 to 28 degrees C constantly. In order to keep the temperature under control im running two fans 24/7 one directly above the plant. i have one white rhino mother about 5 inches tall in there and shes just a bush, most of the leaves on top are curling and the serrated tips are pointing up (srry not able to post pic at this time ) its seems like its either to much wind or to much heat at this point but i dont know which, i basically have to have air moving on the plant 24 7 in order to keep the temps low i know direct air all the time is bad but its either that or or have really high temps. which do you think would be less stressful constant wind or high heat. ( and iv also heard white rhino is very sceptical to nute burn ) think i just have a fussy lady ? i did feed two days ago

this goes for a plant recieving too much sun light
A reason for droppy leaves beside the cannibus forum drill "overwater/underwater" all the time.
Plats maintain their bodies by turgor pressure, the pressure of water on the rigid plant cell. Think of a gladware plastic container: if you fill it with water so much it will expand as much as possible. I can't think of a better example at the moment, btw.
I: The stomata, little pores on the undersides of leaves, respond to blue light and open. If there is a continuous source of light, then the stomata will stay open more often causing more water to leave the plant, not to mention the (II: ) water produced by photosynthesis (water is removed when a carbohydrate is made). III: Although plants don't have a complex circulatory system like ours, they have a pretty cool one. They respond to temperature by taking in more water when the temperature is higher (because of the sunlight). This is called transpiration. As a result they want to cool themselves more, so they release more water from their stomata by this method also. This is one of the explanations for the humidity of a tropical canopy: aside from high temperatures, plants are releasing water which is then trapped under a thick layer of leaves. I kinda went off on a tangent...but I hope that helps.lol. Btw, the more water the plant releases, the less pressure there is to support its structure, causing what you described as "droop."

He'd have to link externally, his current post count won't allow image tags and may not allow links either... I never ran into that issue, my first 2 days I put up 50+ posts and had capability by then.
what's wrong with it? you got any pics?

I didn't know that. thanks for the heads up
i pretty sure this lines up, I just cant find the answer https://www.rollitup.org/marijuana-plant-problems/643632-helping-hand-please-am-i.html
overwatered, underwatered, and/ or just stressed?

The soil should dry out before rewatering if using peat. if using coco you need to keep it wet

Any ideas with whats going on? Im a super noob I know. I havent been really watering them too much

Wow, that's a super-stretch! Lights are not providing enough intensity (too weak) and/or too far from the plant. CFLs can be be jsut a few inches from the seedling as long as they are not too hot.

Ok been looking for the answer to this.. Ive been getting clawed leaves on some of my plants.
I have 5 (unknown strain) plants in 3gal fabric pots. I use a mix of FF OF and LW for the medium.
I use Big bloom and Tiger Bloom as nutes and only since i switched to 12/12 (didnt have the cash for it during the veg cycle).
I use 1/2 strength with the TB and 2/3 strength with the BB.
Ive been watering them with a quart of H2O every other day and 1/2 litre on the in between days. (And I dont PH balance btw)
My question is: Am I watering too frequently? And could this be the cause of the clawed leaves? And can a high or low ph cause this?
