I noticed the same with my plants. This is speculation but I imagine this has to do with it it losing more water to transpiration (evaporation through the leaves) during the daylight hours when it's warmer than it can take up, causing it to droop. At night, when it isn't losing so much water, osmosis outweighs the loss causing the leaves to become turgid. As I said speculation; an educated guess at best. Perhaps this is why plants often do better under 18/6 rather than 24/0.

yeah, that is plenty of light. Is your light air cooled?
yeah it aircooled
itmaybe just a little to warm directly under cause as you will see in the picture the edges are turned up
as curious said it may be a transpiration thing..
i am just overthinkng it cause they are about to hit the 4th week and i want everything perfect for crunch time...
thanks for the input so far:mrgreen:bongsmilie:mrgreen:

After seeing the pictures I'd like to change my mind. I'm not expert diagnostician but that looks like a magnesium deficiency to me. Get a second opinion though before you go crazy with the eposm salts.

A lack of mag will turn the leaves very dark green, like yours, nearly blue. I can see the "V" shape in your leaves setting in. This is how a cal-mag deficiency actually looks in the very beggining. Also notice the red/purple stems, another sign.

Curious Soul is right on with your issue. Good eye Curious.

Very interesting indeed, this thread may have just answered my wonderings too.

I have a few leaves doing the same thing, forming a V and the leaves pointing up some. All looks healthy at this time, plants are due to be cut in around 3weeks, would it be worth me tying to fix the leaves or just leave as is and finish the grow?

"This is speculation but I imagine this has to do with it it losing more water" sorry guy but your speculation is very misleading... when you water a plant the vacuole inside every cell fills with water causing the plant to look "sturdy" or "up-right" or just generally healthy. so when the dude who started this thread stated he saw a "healthy droop" he was already down the wrong path because it will droop when it is lacking water (osmosis: water moving from high concentrations to low). also to the person who started this thread; Im gon guess you are using a cfl or a low wattage/lumen light with out any sort of reflector. your plant is stretching toward the light because it is uncontent with the amount of light it can absorb at its current height and is doing its best to fill its "need for light." a light too far away can also cause your plant to ilongate and become less full or bushy and get skinnier and long. so if your stoned and you alrady forgot that, your light may be too weak, may be too far away, you may not be using reflectors, or re-read the water portion.
i know my cred hear is low because i dont respond to 100's of threads but this is credable info. i have much college level biology and plant biology class, and first-hand expirience.

i am sorry but i beg to differ if you have been around alot of different strains alot of the indica varieties when they are nice an healthy kinda sit heavy and the leaves just kind hang, maybe droop is a bad choice of words...

the point being this guy was trying to help had a honest hypothesis given the data recieved and tryed to help out a fellow struggler..
since you have all that fancy learnin maybe you should have looked at the few post under the one you jumped and you would see i am using a 600 watt so your powers of deduction are shit good day,,,

i am unsubscibing to my own thread and i suggest all others do the same .. thanks pal go to school on class

you've gotten the wrong idea from my message. i criticize anyone who talks shit via Internet which is why i wanted to apologize. the last thing i was trying to do was belittle you or someone elses hypothesis. i was simply rejecting it and giving my own input. my apologies for not reading further down to see what your using for your grow, im nice and stoned (like plenty the ppl here) right now and didnt bother reading anything but your original thread. again my apologies for sounding like a duche bag in my first response. i try to offer quality help not try an make other ppl feel like idiots over the internet.

:eyesmoke:thanks for clearin it up . sometimes it seems that people are afraid to give well thought out answers to problems because the get berated by some weed baron..not that you are mind you..just in general..
now we all must take responsibility for the actions we take with our plants, thus not jumping at everylittle bit of advice given,, but we must all be willing to accept any and all well thought out reserched answeres from folks... may we all be well stoned and thanks for any responses;-)
