What the heck is going on here?

My plants were growing really nicely until about 2 days ago.

I had reduced the nutes to around 800 ppm and after about 2 days this started up. Is this a nitrate deficiency or something else?

White Widow
3.5 weeks old
PH is at 6.0
I rasied the nutrient level to 1350 ppm thinking this was nute deficiency because it is the first time in near 3 weeks since I added fertilizer (the ppm was at around 800 or so when I thought they were suffering from nute deficiency)
Using a 400w mH light 18-6 hours
temp is around 83 degrees
humidity is 69 %

It looks like so many different things. What should I do now.

Please, any help will be appreciated.

Same thing happened to me, are you using tap water?

Tap water wrecked my plants in 2 days. If you can get RO or distilled water, use that instead.

Sounds like your ppm is high for the size of those plants.

some water + superthrive should fix that. ONe gallon + one drop of superthrive.

thanks for the heads up guys. I realized this evening that it was the tap water that was "actin awfuwy scwewy, huh huh huh"
Der !!! Man, when that light bulb came on I nearly got a headache. Usually when I figure something out, it comes on slowly, primarily because that's the way I like it.

my plants had the same thing. i use RO water. ehh. i just said fuck it and let em grow out and they turned out great.

Using tap water is just fine. It's a myth that it hurts your plants bro.
There is not NEAR enough chlorine in municipal water to harm plants, if it
was THAT high, you would be sick too.

There are actually many beneficial trace minerals in tap water, and a little
chlorine is a good thing.

What you have looks like a slight nute burn, or a magnesium deficiency. Flush them
and all should be fine.

not nute burn im pretty sure I would go with a def. of some kind leaning toward mag.

Problem is he's in dirt dude - Chances of mag def in only 3.5 weeks is slim and none.

It LOOKS like it - but Im pretty sure it isnt. It shows classic signs of tissue burn - either by nutes -

or the Light is too close ?

Thanks everybody. I have changed out the water already to distilled water and a low dose of nutes. I was also leaning towrds a magnesuim deficiency. It came up all of a sudden. I had changed out the water from my initial setup (distilled water). Whatever the case, I believe it is gone now. I plan on just leaving the leaves alone and let them fall of naturally. I don't like the thought of cutting anything. Otherwise the plants have been healthy and the envorinment is about as perfect as I can get it with what I have available. I thank all of you again for responding. Your input is wanted and appreciated.

God help me if these plants make it to harvest. They will be the most illadjusted kids I've ever seen. They have been through hell and back. 3 of the 5 were a very generous maybe survive at germination.

While I have your attention, is there a certain way you would place the sprouted seed into the rockwool cube? I have read differences of opinion. Some say to place the seed in with the tap root pointing down which would mean that you place it with the open end upward (allowing for the natural curve of the root to point down). Others just say to put them into the rockwool. Last thing I want to do is cause stress at that critical stage. I was just wondering what worked best for you all.

Thanks to my new friends, I just may succeed (feel like I need to rhyme using the word weed now).
