yo im starting to get these light yellow spots on some of my leaves. its about 2 weeks old. and how much water do i feed it at this stage? do i give it any miracle grow or chemicals?? help
at that stage when only water when the top is nice and dry almost dusty/crusty until an inch deep where it should be a little more rubbery but basically what jardann9e said above. whats the temperature of the grow room, if its above 85 thats prolly why u got the yellow, too much heat drys the leaves out real fast. give us some pics!!! good luck bro
Have you used nutes already in the grow??? if so it sounds like nute burn in which case id flush for a few days and stay off the nutes for a few weeks... if not it could be Potassium or Nitrate defficientcy in which case i would still flush for a few days and see what happens.. if the problem remains or gets worse buy some of these: http://www.lovethegarden.com/products/plantfeed/mgsrallpurpose.html... These will ensure the plant is being fed but not stress the plant....
Good luck.. hope they pull through...

My grow in my sig, no nutrients except slow release. Don't over generalise on something if you don't know all the facts. However miracle grow is not what i use and is crap and i agree on not using nutes on seedlings until a month old.
