Yellowing lower leaves

bio1 · #1 (**permalink**) 04-09-2008, 02:47 PM

High!

My Plants are 5 days into veg now, I killed the males and there are 4 females and one where I cant tell its gender yet.

on 2 of my plants the lower leaves are yellowing, no brown spots and the leaves are flexible (when i nute burned my "test" plant the leaves got crsipy so you could break them), they just seem to have lost their vigor...

all other leaves are still in good condition and i am feeding them only a very small amount of nutrients, so that shouldnt be the problem? my ph is good too...

is this a nitrogen deficiency? what to do? more nutes? ... maybe i can take some pictures later when i get a camera

Yeah looks like nitrogen deficiency. If your pH is good, I would assume Nitrogen Def is the other plausible explanation.

I have the same on my plants that have been flowering for a few weeks.

I agree they mostly look nitrogen hungry except for the next to last pic I think it was. Feed them the food high in Nitrogen.

I'd like to know this answer as well. Is there any chance for a damaged leaf to really revive itself or should you just trim it.

I leave everything that's still green. If they're more than half gone then you may as well trim the whole leaf off to give room for your other leaves to get light and also so the plant doesn't waste any more time on the dying leaves.

The plant doesn't waste time on dying leaves, it just draws the life out of them when they become surplus.

It is perfectly natural for lower leaves to yellow and die.

what size pots are these in maybe the roots are running out of space if you used lower concentrates of nutes i dont see them burning

The roots running out of space does nothing to the plant above... it will not cause overnute or undernute. The plant will just keep growing.
