I have a couple plants that I started from seeds and one isnt looking that well, the rest are a really really light green so I dont know if that means their gonna start lookin like him soon too.

I noticed it a couple days ago and didnt want to freak out over nothing and it doesnt look like its getting better so I figure theres something I need to do....

Looks like nitrogen or potassium deficiency but I could be wrong.

How often are you watering them? What are your growing conditions?

Btw, that's a beautiful looking sativa strain you got there, hopefully it perks up.

the 3rd picture looks like it might be heat stress. what are your temps like?

420- Thanks, I water like every other day. I'm growing in the garage, it doesn't get hot in the daytime and it doesn't get too cold at night. I have an intake and exhaust fan in the storage bins, but only use the exhaust because with the intake it gets toooo cold...

Ganja-I don't have anything to read the temps =/, guess I should invest in that asap.... It doesn't feel hot at all though when i put my hand in, even right next to the lights.. I have CFL's and their probably a good 4-6 inches above the plants right now... I moved the plants down a little like two days ago cause i thought they needed a little room.


Does anyone know of a product I can get at a Home Depot or some kind of gardening store that isn't expensive that I could use for plants in this stage?
