New growth turning dark and looking wilty

Hi guys and gals. Got a problem with these White Widow. What do you think? New growth sites are all turning nasty. Growing in cococoir in smart pots, ebb and flow tables. 1000 watt light canna coco nutes. I burned sulfer pearls last night and I hadn't noticed the new growth looking weird before. Anybody seen this before? Ideas? Plants health except for this all a sudden.

Looks like root rot symptoms.


IE... anaerobic conditions.

I had a week old seedling that just collapsed one day. I figured it was toast. I pulled it out very slowly and the whole tap root followed. It was not as white as it should have been I put it in a cup of water with a touch of peroxide. It lived! About a week later I could see little hairs growing on the root. I replanted it and it caught up to the others by the time it went outside.

by burning sulfur pearls you mean what?
i know of sulfur pearls being used in aquatics.

Like MJ said possibly root rot and the beginning of an infection.

Another guess of mine is a toxicity caused by chemicals.
Is there a chance you spilled any chemical or used cleaning agents at something that comes into contact with your nutrient solution?

If not, look for your rootzone.

Sulfur reacts badly with oil based sprays for pests and fungus, have those plants ever been treated with anything besides sulfur?

If not is your humidity low?

Fusarium wilt or something goes wrong with sulfur.

Thanks guys for your suggestions. I haven't treated them with anything except burning sulfer perls. I was hoping perhaps someone else had experienced this symptom before and could identify it readily. I wonder if I maybe had overnuted them except I have normally experienced just the burned leaf tips when I have over fed plants before. Has anyone experienced Fusarium Wilt before? Does this look the same?

Thanks for your feedback. I think I figured it out with your help. I didn't think to turn off my light and I must have burned my tender new growth like this video shows. https://www.youtube.com/watch?v=-TZr58mfDrE
