HELP - Dropy and yellow WhiteWidow

[luckychiken]

Hi everyone.
I got 5 plants. 4 looking great, 1 not.

This WW has been yellow for the past weeks.
4 days ago I added some Iron to the soil.
I water every 2 days.

Today I found it really dropy. Like falling down, on each branch.

Should I wait longer for the Iron to take effect ?
Have I messed up adding Iron to it ? I thought that was the problem.
Should I add 15-15-15 ? We are currently into 12/12 flowering stage.

Here are some pics of everyplant 3 weeks ago. Now WW is a lot more yellow and dropy. Like in the pics attached in this thread wich are from this morning.

How can I save it ?
Anyone ?
Thanks

thread about the plants 3 weeks ago when the problem was not so bad.

In what form did you add iron?
That's a very bad N def, you may have locked yourself out pretty bad. I see something else going on with the coppery hue on some leaves. Like a toxicity.
In the other thread, the plants were already startign to look pot-bound- did you repot?
I thik you are going to have to flush heavily, check and adjust your pH if necessary (likely IMHO), and get going on a veg fert with plenty of N in it.
And repot!

iron in form of crystals wich I used into the soil. I made holes and put it in.
Then I watered. 2 times already.

Why do you think to repot ? All my other 4 plants are growing great in these pots.
What good would it do ?

I can do it. But I would like to know why.
As for flushing. I will do soon. If that´s needed to take out whatever harm I did.

What is IMHO ?
So...now....flush a lot... how long ? And add veg nutes.
Got it. Anything else .--anyone ?

Iron CRYSTALS? Where did you get them? What did the package say? Ferrous sulfate perchance? let's hear it for sulfuric acid... yikes.
IMHO=in my humble opinion.... you must flush and feed with a nice veg fert at half strength. then go back to bloom ferts if that's what you had been using.
