Anybody know what is going on here

My auto plants seem ill and I cant figure it out. pH is 6.0. But my plant is dying. Things I've changed is I've added 2 600w phizon dimable led lights. Last time I was using 20-20-20- general purpose fertilizer. Now I'm using GH flora nutes, and i was following the nute schedule you see. and I got a 2x4x6 grow tent. I used a 18"x18"x6' wodden box. with 4 23w 6500k and 1 2700k cfl bulbs with no problems. Any help would be great. Thank You

i've done week 4 on schedule. I'm not sure, but is it a cal/mag deficency? I have hard water. I didn't think I needed it.

Did you follow the nute schedule exactly? With the dosages they suggest?

Yes. But the cal/mag. my water is 150ppm. I don't think I need the cal/mag

That probably your issue.

Most nutrients need to be introduced slowly.

Generally we begin at 25% of reccomended and go from there.

I have had instances where 25% was too much.

Just search the site here with that little magnifying glass at the top right for introducing nutrients.

ok thanks. This is a custom feeding schedule I found online it is less then General Hydroponics suggests for Deep Water Culture. For the person who made the schedule said the same thing you're saying. I'm wondering if this is for photo sensitive plants, not autos. Shit never thought of that. I must find the article. Thanks again.

That is end stage Cal/mg defeciency.

You may lose the plant if that's all over.

Calcium is one of the fundamental building blocks of life.

Thanks.

Well I bought calmagic from Amazon. It comes tomorrow before 9p.m. I hope it can save it. And help the little one I have at week 2. Thanks for all the help. I'll get back in a week with an update. or sooner, we'll see.

Looks way over ferted, which is causing burn and lockout.
What soil/medium you using?
I bet your medium ph is too low from nute buildup and maybe you are using an acidic medium like peat.
I used to get the same symptoms from tigerbloom and promix mid flower.
Also any idea what ppm your feeding?

There’s most likely no coming back from that.. your yield will be greatly reduced if you get anything

I know, it's not the same as my other plants i grew in my old woden box with cfl lights. and regular cheap fertilizer.

I cant imagine 400 ppm burning a plant that size like that.
Whats the temperature inside the tent? Humidity?
A ph of 6 seems to be the higher side of dwc also, from what i read.
Roots look healthy?

I know. My problems started when I started using led and a grow tent. I grew my plants with a wooden box, mylar, 4 6500k cfl lights and 1 2700k cfl, regular fertilizer and root farm bloom when it was blooming time. I always kept my plants between 5.5 and 6.5. I never had a problem till I used the tent and leds to grow more plants at once. And I always used autos. The basement is 72 degreese, don't know the humidity or water temp.

I think the water was cooler in the box because it stuck out the bottom of the box I made on to the basement floor, for more grow space. I might sell the tent and shit and go back to individualized boxes with cfls if the new nutes and calimagic does not work.

What’s your tap water like (analysis)?

it was 150ppm I tested my new truncheon meter on it. and apH of 8. all I know about it. it is not a commercial grade one. none of my meters are.

Can you get your municipal water analysis particulars? They usually list the ions by concentration. Usually the water contains calcium, magnesium, bicarbonate and sulfate ions . These are benign or nutrients.
Sodium and chloride are non-nutrient ions whose presence interferes with nutrient uptake. Thus my interest, and my guess that you’re not on a well.
