its about 3 weeks old
i have given it very few nutes in very low doses. (9-12-12) at 1/32 strength just twice one week apart, 3days ago and 10 days ago
it is in a mix of potting soil and seedling soil bout low in nutes
i only water when the topsoil is dry to the touch which is about every 3-4 days
also it i just this leaf
the only thing i can thing of is burning from the light possibly b/c that leaf was kinda close to one of the lights but i backed that light up just now and rotated the pot
all help is much appreciated!!! thank you in advance!

what kind of light, how far away? maybe you splashed some nute water on it?

i no i did accidentally splash some water on it from a cup that did have nutes in it... the lights are 26w cfl's mixed 2700 and 6500, the one that was on it was a 2700, and it was 1-2 inches away, and there is a possibility i got some nute water on it 3 days ago

i wouldnt worry then, if it starts moving to other leaves, flush her, then hit her with a very light dose of ur fertz, maybe 1//4 strength, i find that helps almost everything, evrery time..

COOL! thanks man!
