Leaves turning light green, then yellow, and dying (pics)

I'll notice a couple at a time turning a light shade of green, then they turn yellow and get brown spots. Then the leaves die. Its not all of them, just ones near the bottom half of the plant. The plant is in week 3 of flowering. Please help, heres a pic!

probably nute burn, from what I've read that about looks like the problem

It looks more like a deficiency to me. What are you feeding them, how old are they and what system are you running? Good luck JR

Oh yeah any bugs on them leaves, look close.......

What kind of deficiency? I am giving half dosage of 8-12-9

bump ?

nute burn... stop adding nutes for a few days and flush. if the problem persists after flushing, we'll see what else it can be.

what about N definciency?

no, if it was N def, the whole leaf would have turned yellow all at once, not localized like this.

try this to be sure. stop adding nutes, maybe even flush the soil. if the problem goes away, it was nute burn, if the problem advances, it's N def and you can add nutes.

Look in the general forum under problems, It looks like a deficiency in Iron or Mg. I could be wrong. Look around at the pics and see what looks close to yours. Good Luck.........JR

be sure the nutes are not getting on the leaves also....JR
