Vegitation Yellowing Leaves (PICTURES)

I just put some new clones into my veg room and some of the leaves are turning a weird yellowing color. I usually cut these off but this batch is doing it on all the new clones. Any ideas on why this is happening and how to prevent this from happening?

You cut off yellowing leaves? Even partially yellowed leaves?


Those cubes sure dont look wet, and what light are you using, and fertilizer solution, come on if you want help you gotta tell us what youre doin

The person I learned from taught me to always remove the yellow leaves as it supposedly takes away from the plants energy if they aren't removed?

The cubes are wet, they are just brand new but they are wet! I have a MH 1000 watt light. I also have a 1/2 strength solution of my normal veg solution for these.

I'm also having this problem with my plants. They were yellowing. But I was overnutrientiating (can't spell) them with AN Tarantula. So I cut back with a water change yesterday so i'll see what happens and keep you posted.

dude, what's up with the green shit on your other rockwool cubes?

that looks like a definate nitrogen deficiency to me..

go to the grow FAQ at the top of the screen and then go to plant problems... then the deficiency tab... etc.

seek and you shall find
