Brown spots on only one plant =(

Hey guys.

I have 5 plants, 4 seem pretty healthy, they are about 2 weeks from seedlings, and one of them has become a bit gimped.



First 4 plants look ok but the fifth, well, you can see. Last week this one had one large leaf and one small leaf on the top, and generally looked like the runt. But it was healthy. Now it has gone a bit manky. All 5 plants are fed the same solution, 1.6 EC, 5.8-6.0 PH, the light is a good 20+ inches from the tops of the plants, and the temp/humidity is 25-27 degrees and 45-50%. The soil was moist under the surface, so they are well watered. Checked under the leaves, no bugs or spider mites. And they never get the leaves sprayed or watered so i know it isnt scorching.

So, any ideas guys? =)

Water in some nutes high in N and in a week they will be back to a healthy green and keep feeding as per instructions. Hungry plants.

thanks mate, and great avatar. =D

Yea, as long as pH is ok, and your not overfeeding, then keep feeding.

you should go buy some scissors too. its gonna be time to cut those in half soon.


EDIT: yea i might have to take that last part back. after looking at them again, i might even cut one or 2 in half right now. Start reading up on cloning, topping, fimming, and when your ready, cut that bitch.
