Leaves Curling UP w/ PICS

Id raise that light, looks like its burning the tips to me...Just my .02

Ive been having the same problem with my babies at first I thought it could be a nute problem but considering I have not started Ferts yet and they have been planted in happy frog soil they should be fine since they are so young. Now I did some interesting reading On a hydroponic site where a gentleman claims the reason why the leaves curl is because the air is either to dry or the soil is to dry. Most likely the air and that the roots can not suck up water fast enough to cure the leaves. where I live it is very dry so the grow rooms humidity level is around 20% so with an HID lamp I can imagine how plants might be burned. I created my own make shift green house around the plants and put the humidifier inside. Otherwise its hard keeping moisture in the air with the exhaust at the top of the room. So far the plants thats leaves were curled are still curled however the new foliage seems not to be curling as bad with the more humidity and the light further from the plants. All let you guys know how it goes. If yall figure anything out let me know as well..

looks like a cal mag defeciency to me try addin a little more cal mag and see if that helps....i try to stick with 18inches away from the plants with my 1000watt hps but they have even got closer down to like 15 if i dont pay attention. As long as you can hold your hand unter the light for a lil bit without discomfort you should be fine...no hotter than 85 degreese but 80 is cool( pretty hot for night though id try to keep it around 70 at night 65 maybe)... hope this helps... good luck

ive heard this is called praying for magnesium when then leaves fold in like that, at least thats what i refer to it as

yea lots of good advice so far, spray with distilled water, raise the lights, add more fans...

also, check the temp of the water, if its warm/hot already, then evaporation (and curling of the leaves) happens quicker.

RyI have this problem on my 3 week old Aurora indica plant. I never thought of wind burn or stress. Makes sense tho cuz my little fan is rt next to the plant. I'm gonna move it now. I thought it wud help make the off shoots stronger. Here's pics

The yellow is from the 2700k bulbs I have mixed in. There's no other problem. Did just fight fungus gnats but that was a lot easier than peeps made it sound

from a newbies not over thinking/common sence/just noticed myself point of view on your particular situation id say that's most likely either under watering/underfeeding.. or a bit of wind burn if its not heat issues or over feeding.. i cant imagine it being anything else but like I said im a newbie it could have something to do with humidity for all I no lol

make it more humid so your plants don't dry out from the wind maybe... gonna try this myself ima genious lol do this by spraying plants with water and putting a bowl of water in area also the biggest and best info your gonna get is to learn to take things 1 step at a time don't be like me and overthink and stress yourself to tears everyday trying to tackle everything at once lol the people on here and the shit they no will make u feel like giving up but unfortunately the best way to waste your money and time is on trial and error in this game be patient and if it becomes a stress just say fuck it n deal with it when its really a problem im dealing with nearly 40c temps atm and although shits not perfect its still working.. ive finished 1 crop n got 8 ounces off 4 plants with 30 days veg lost some to mold due to high humidity in flower but the humidity/temps in my area are all over the show the weather here is fucked 1 day its 2 cold next day its 2 hot letalone humidy changes lol just take it as it comes brother

Looks like too much air being blown on them bitches
