Hey like it sais in the title im kinda a newb i wanna wait till i can clone it to determain sex. as i have read there is now way to determan its sex without subjecting the plant to a 12/12 cycle and start flowering. and dont wanna go through the hassle of finding more good seeds... here are a few pics one specificly showing the tops two sets of leaves begining to look a bit dry on the ridges and curling up... i think this is becuase i read that misting was good but didnt read not to do it under the light or expose it to any light will doing it... least thats what i think i want some input :) ... also other plants seem a bit fuller at this age is there somthing i should be doing to promote a fuller grow... also i am using 2 t21 fluros one is an ott lite true color and one white i read that these cool whites produces more of somthing and that promotes a thicker grow prior till about 1.5 months i had two ott lite true color bulbs.

hi im no pro but your low power lights wont burn your leaves when watered if you had a mh or hps lamp then its a big no no and yes you can take a clone and force flower 12/12 to sex plant as for you bulbs i think if you have full spectrum you have no worries
as for growth boost high nitrogen feed and more light

Depending on light set-up, environment... your plants can show sex in as little as 28 days of 24/0

In essence your plants will show sex while still in vegetation.

right know i am giving it 18/6 hrs have since it was a wee one when i did give it 24/0 but its twice maybe three times that age dosent apear to have any sign of sex least im pretty sure it doesnt.

"hi im no pro but your low power lights wont burn your leaves when watered"

do you have any suggestions as to what might be the cuase of the leaf curl... my soil ph is like 6.9 and doesnt seem to change much... which is a good thing i believe... and the temperature in the room and right above the plant is not too hot...;
how long should my stems be that i want to clone?

Well I am a pro'... and I can tell you for a fact that it is heat stress. The leaves curl to decrease surface area to the leaf, to prevent transpiration.

You need to lower the temps.

i would top that plant, but the leaf curl could be the start of Magnesium deficiency, try adding some epsome salt 2tsp per gallon of water, but i also don't see any burn marks maybe you need to up your nutes.

Could be's and might be's are not nearly good enough... it is clearly too hot in there. All good growers know what heat stress looks like.

too hot under t 12's? if you knew anything those don't put out enough heat to cause that kind of leaf curling. get your facts in order before you start calling people out.

4) Leaf Curling Up - Leaf curling up can be a sign of a Magnesium (Mg) deficiency caused by too low of a pH level. Magnesium deficiency will show as a yellowing (which may turn brown and crispy) and interveinal (in between the veins) yellowing beginning in the older leaves. Interveinal chlorosis (yellowing) will start at the leaf tip and progressing inward between the veins. It could also be a sign of excess heat and humidity in the grow room.
 Solution - Check and adjust the pH level as necessary. When the pH is not at the proper level marijuana will lose its ability to absorb some of the essential elements required for healthy growth. If you’re growing in soil Magnesium will begin to be locked out at a pH of 6.5 and lower, in hydro it starts at 5.8 and below. If the pH is correct, then add 1 teaspoon of Epsom salts per each gallon to your water. Or, to foliar feed them, add a ½ teaspoon per quart to a spray bottle. **Note- If your tap water is over 200 ppm Magnesium will be locked out due to the calcium in the water. Magnesium can get locked out by too much Calcium (Ca), Chlorine (Cl) or Ammonium Nitrogen (NH4+). If this is your problem we suggest using bottled or RO (reverse osmosis) water.

Actually in an enclosed space it can always be too warm. No matter what lights you are using.

Looks like heat stress to me too.

Great post, but completely off the mark... and obviously posted by someone that has never actually experienced an MG deficiency before. Those leaves are curling because there is not enough ventilation, and it is too warm.

cut n paste is very unprofessional... and shows that you really have no idea of what you are talking about.

cut n paste or not... IT SAYS IT CAN BE A SIGN OF HEAT OR HUMIDITY, so he isnt wrong...

This is heat stress from my plant




i dont see the blistering on his leaves, allthough because its happening closer to the top leaves, i would check your temp at the height of the leaves to be sure, i cant belive that a t12 would cause that

Yes it is a very strange site... so large, yet so little people who actually know what they're talking about. I see why this site is a bit of a joke across many other, decent forums.

I've found that too... it seems that there are a lot of people here that like to pretend they know what they're talking about. That last 'heat stressed' plant was very funny. Clearly undernuted... seems like they get things backwards on here.
