Hello everyone,

I am a new grower and I have some 2 week old seedling. Most are doing very well, but one of the apparently healthy youngsters have a couple of yellow leaves.
Any ideas people?:leaf:

Noob advice ,
where it says Location , change the Uk bit ?
are you seriously that stupid ?
No areas of the Uk are legal to grow,
good luck.
 
No purple leaves yet, but despite the slight discolouring the rest of the plant seems to be doing okay. My assistant did slightly over water them at the start, but I got onto that fairly quickly. Only got 13 out of 15 seeds.
 
a IMG_0044[1].jpgIts not much of a picture, but if you squint you can see the leaf earest to the camera is yellowing and has brown spots too. otherwise it has really good roots
 
Hard to tell from the pic exactly whats going on but here you go. N is a very common deficiency that causes yellowing in young girls. You might very well be deficient in N, but I find a common reason N gets locked out especially in small plants is over watering.

Now from your picture what stands out to me is not the deficiencies, but the yellow spotting. Could be a number of things from burns due to foliar sprays, or my first instict would be bugs. I'd get a magnifier on those leaves, make sure to check the bottom.
 
No worries mate, I should be more careful. Its being in the middle of nowhere you lose a bit of street smarts. Can't get the sunglasses to cooperate. I hope this pic is a little better. I think my helper is spraying the plants without lifting the light further up. Could this be a cause, because apart from a few runts in the litter, they seem to be doing well. After two and a half weeks in total they are about 4-5 inches. The better of them have several (9-13) leaves that are broad and quite long. Plus I have one that has a real curly stem because it went nuts and tried to burrow down. (So i levered it up and staked it - but it isn't growing)

Thanks mate, they were over watered originally. Now I have been watering fully once a day, twice at the most, and spray every hour. Although my 'helper' can be a bit heavy handed and hasn't been lifting the light after spraying. What am I looking for with bugs, and is it worth spraying for them anyway?

Watering everyday ?sometimes twice ? to much umbre.....
Becareful not to overdo it , the roots will drown and rot....
 
Hello again, sorry to bug you, put the four suspect leaves have turned into crisps. All of the other plants are doing okay, but I am worried that I have a bigger problem. I have stopped spraying and put the grow lights to a higher point with about 4 feet clearance. My temperature could be a bit high at 37 degrees because I have installed another 600 light on them. The 'well' seedlings are doing a lot better for it, but I fear that my poorly girl is frying. I was thinking of putting a dome over it (half a plastic pop bottle) to try and increase the moisture around the plant. What do you think?
