Plants dying all of a sudden...I hope they can be saved (6 mos. old)

First time grower.

I've been on here a lot, but never posted.....

We have 9 beautiful babies, almost 6 months old. They are under a 3-bulb LED (blue) (I know, many people have told us these lights suck, BUT we have been very happy with them & growth has been great) & have been 24 hour this whole time (we were planning on changing to 12-12 this wekend, BUT....).

They were absolutely beautiful & healthy & thriving ...until a few days ago.

Nothing changed in the environment, we water them regularly, there is great ventilation & air, warm enough....

One of the tallest started wilting down from the top down, we watered it, it worsened, so we cut the top 1/2 off (!) & it still completely died & wilted down.

We fed them liqiuid fertizlizer & watered them thouroughly...

Today the leaves are yellowing, there are brown & yellow spots, which when worsened start to become HOLES through the leaves!!

Please help, I have posted the best pics I can. There doesn't seem to be any sign of bugs, a few knats were in the soil but not anymore & 2-3 at most...
A friend said it looks like a fungus or from the knats (which I didn't think could make such a huge impact on more than 4 plants!). I know yellow is from over watering, but i also know I haven't over watered...

Not sure what to do & would hate for them to all die when we have been working on them for 6 months.....THANKS FOR YOUR HELP!!!!!!!!!!

what size pots are they in?

Hmmm.
I don't know, you should fill out the form. But, one thing that I saw in the pictures makes me wonder. Do you have a magnifying glass or jewelers loupe? Get one of your leaves, and look underneath of it, the bottom side. Do you see anything?
You may have spider mites, but you may also have other issues on top of that.
Actually, look at more than one of your leaves, don't know why I said 1, but really look closely. If you see any little egg looking things, or little tiny black specs flipping you while taking a shit, then you do have mites.
But you may have other issues. You would do well to fill out the troubleshooting form. Good luck. If you do have mites, go to home depot and get some no pest strips. They work great. Probably better than anything else you could try, and easier.

The pots are 12"...They aren't coming out the bottoms, so I didn't think it was a size issue.

I'll fill out the form soon (out the door now)

We're getting the strips, just in case....

THANK!!!!!!!!

im no master diagnoser, but you could have a whole slew of issues.

Rootbound- check the sides of the pot, if you see white roots...its rootbound and you need to transplant them into larger pots.

Salt build up- have you flushed them? fertilizers have salts in them that overtime build up and cause the roots not to take any nutes in. therefore making that fertilizer you gave them when they were hurting useless.

Fertilizer burn- too much fert will kill them. If they are weak and wilting.. DO NOT give them fertilizers. its too much for them, its like a human O.D.ing on tylenol. the stuff's beneficial, to a point.

why have you vegged them for so long? 6 months is a little nuts, to be perfectly honest. Normally, you can go through almost 2 whole cycles in that time span(veg and flower)
sounds like you need a new light.
spend the money, sell one of your harvest's to cover it. itlll pay for itself in one harvest

hope this helps...good luck and keep us postedimp:
