This has been slowly getting worse and worse each day, but looks to be in the beginning stages of some type of deficiency. Soil grow, has been nuted twice with 1/2 strength Peters 20-20-20. Sorry for the blurriness, its hard to get a clear shot under HID lights with a cell phone camera. lol



Any ideas?

Temps never even hit 80. I sit at 78 with the lights on, and like 72 with them off. Im running an 18/6 light cycle.

The only thing really wrong with my setup is my humidity, which I dont think would cause these problems, especially since none of my others exhibit the problem. My humidity was as low as 20%, but Ive gotten it up to around 50% the past few days or so.

Damn, that leaves a couple more things... either some sort of nute def. or nute burn. Hard to tell from the pic, any purple stems? Purple stems usually mean either it's cold(which it's not) or there is a pottasium def.

A picture speaks a thousand words. With many of the ailments that our plants can suffer from, the vast majority of them can be identified with a simple picture. Making me play 100 questions didnt really do anything except state what the picture already told you.
