Need help. Fungus? Nute lock?

Not sure what's happening here but it appears to be slowly spreading from plant to plant. I had a few theories. First I thought maybe I over nuted them. Then I thought maybe they had chlorinated the water recently (I know, I know, I need a filter). Then I thought maybe a disease or pest or more likely some type of fungus but I've never seen plants present like this. Any help is greatly appreciated!

Welcome to RIU

What are grow media, nutrients, feed/water sched, ppm/ec, pH, temps, RH, light specs and distance? More info is better.

Organic soil. Every other day, nute, nute, flush cycle. I need a ppm meter but I run ph around 7 for flower, 6.5 for veg and 5.5-6 in the aerocloner. These plants are under a 600 watt led, about 2 feet from the canopy.

There's not enough chlorine in water to do that and plants actually use chlorine.

Looks like you either fried them either with nutes or light too close or you have a bad case of the bugs.

Get better pictures in natural light.

I'm not an organic soil guy, so I dont know the ins and outs of what could cause the issue from that perspective.

Have you inspected closely for mites under leaves or in the soil?

I didnt know to check the soil but I'm intimately familiar with spider mites. That is DEFINITELY not the issue but I know theyre not the only pests. A friend of mine got aphids on their indoor. :shock: I'll go pull a couple leaves and bring em where I can actually get a pic and take a peek at the soil while I'm in there. Those led's make it impossible to take a good picture.

It's only effecting top growth from what I can see from the pics. Heat light or both back to back feeds aren't great either tho. If you're watering those plants every other day you're either not giving them enough water or not letting the pot dry out enough in between waterings. Also always giving a set ph isn't ideal in soil. Nutrients are absorbed at different ph levels. Depending on how organic you must ph using liquid nutrients but using organic soil with organic nutrients the soil or microbes rather buffer the soil for you.

Check lights owner's manual or amazon for distance check plant canopy temperature back off the nutes and give more water. Those plants may not be worth saving.

Seedlings or early veggers are okay to water daily or every other day, not root filled pots

So, some of the plants effected which it looks like it will be all of them soon, are at least 3 feet from a t5 so im mildly skeptical but I know my skepticism means nothing and some of the plants were closer than I thought to the lights so I accept the premise as a very strong possibility. Regardless of how this turns out which will probably be me scrapping the whole room and starting from seed, I will definitely be paying even closer attention to the distance. I didn't see any signs of pests although I don't know what to look for in the soil. Temp in the room is right around 70 and there's oscillating fans moving the air around.

If you're feeding those the same you've burned them up with back to back feeds. I veg under a t5 like a inch away. They'll burn due to growing into the light that's about it. Florescent light is only good for about 12 inches away from the bulbs

I veg under eye hortilux power veg florescent bulbs

So I work at a big medical grow. We feed/feed/flush with great success but it's far more specific hand tailored nute regimen, not one size fits all FF bullcucky made to sell nutes, not feed plants. I have no problem switching to every other watering and in my case it's probably more ideal for what I'm doing. I've always said less is better so I'm not sure what happened but my first thought was nute lockout.

Yea you were using ff more than their nutrient line suggest their suggestion is already entirely too much. I didn't know of weed forums when I started growing and taught myself how to water based off of ppms. Like 150ppms calmag 150 ppms big bloom 200 ppms grow big examples. I followed that ppm guide for feeding and run off readings. Based on R/O water with a base ppm of 0

Start at 1/4 strength watch for burned tips before increasing

What organic soil is it when did you start feeding. If had a good organic soil you could have started feeding early, before they actually needed it. Also your ph could have been or be off, depending on how organic the soil is it can buffer ph without phing water. When I used liquid nutrients and happy frog/ ocean forest I wouldn't start phing water until I started feeding liquid nutrients which was about 6 weeks in.

Organics feed the microbial life ( mycorrhizae) around the roots ( rhizosphere ) the plant tells the microbes what nutrients it needs and the microbes slowly break down the organic matter feeding the plant. The slow release fertilizers don't actually technically feed the plants they feed the life around the roots. That life ph's the soil perfect for them to thrive. Liquid nutrients are readily available for plant consumption, and don't work with the rhizosphere therefore you have to adjust ph in between 6.3 and 6.7 since nutrients are taken in at different ph levels.

Broad Mites maybe? Sure looks like it.

6th picture, backside of leaf. Upper left and bottom right. What are those?
