Flowering, but leaves are yellow and dying - Please help

Hey, so here's my deal....

I have two plants. Both started as feminized seeds. One is White Widow, the other Easy Bud.

I vegged for about 7 weeks and now I have been flowering for about 4 and a half weeks.


Most of the lower leaves on both plants have died or fallen off. There are a lot of bud sites, but even some of the leaves by the flowers are yellowing, curling and dying.

Using 400 W HPS with relighting bulb (supposed to be similar to hortilux). Used 400 W MH for veg.

The only ferts I'm using are Canna Flores and I only use it once every 2 or 3 times I water.

What should I do? Is this normal? And how much longer should I flower?

Thanks!

More pics...

Over nute maybe?

wow thats a shame... id be freaking out.

your plants have a nitrogen def,at what time did you stop using veg nutes?

I´m no expert but it looks like over nute burn....and how far is the hps from the top of the canopy????

Hang in there chief.. they are gonna get bigger.. i see ZERO brown hairs...

i stopped using veg nutes when i stopped vegging. so that was 4 and a half weeks ago. at that point i switched to flower nutes.

hps is about 8-12 inches from main colas and 20 inches from other bud sites...

anybody got any suggestions? do plants look good otherwise?

can anybody suggest anything? thanks in advance

flush em, and then let them recover and start over w/ nutes....
read this article about flushing them in the bathtub, makes it a little easier..
forgot the link to the article, but basically it said:

fill your tub w/ water, and then set your pot in the tub and the water will soak to the top of the soil from the bottom ( let sit there for about 5 mins ),
pick the pot up and watch all the yellow liquid fall out..
repeat same process until water comes out clear... i had to repeat 3 times w/ 3 gallon pots..
FYI ..... i use those cheap , plastic pots, and they come pre-holed, but i have found that the water does not drain properly from just the 6 holes.. i drilled holes on the bottom of my pots, and drains alot better...

also the guy at the grow shop that i spoke w/, told me to not let the soil get too crunchy... ( i had read somewhere on these boards that it was good to do that so the roots can get oxygen , and i was doing that!) it's not goo to do that, when there is no water for the roots they start to pull moisture from leaf's...
just some thoughts!

i am working on my first grow , so i am far from any kind of expert...

GOOD LUCK
