Hello,

I have a few plants that are DWC in a tent. Environment is dry with good air circulation, and is 68 degrees F. atm. Some of the boron leaves on a few of the plants look like the picture. Does anyone have any idea as to what they are? Kind of look crystal like. The stems ate also dark and vieny.

Probably edema. Excess watering. Will go away eventually. Decrease watering.

Thanks for the replies! 
 
Yeah i'm kinda stumped as how to water them less they are a hydro plant? Now i did add a fresh 2.5 gallons of nutrients this last week and its when it started. So do you think that maybe there is to much root submerged now? It has a huge root system fills a 5 gal bucket.

Salt build up maybe?
