Opinions on what this is.

Coco...dtw....H3ad formula.... the only thing I've done different is I added 2ml clorox per gallon last night, but my ph probe was acting wacky also, so I pulled out my old one, seems fine now. Too much bleach maybe? Opinions?

Looks like classic calcium to me....but I have no idea how bleach would react to a plant.

Chlorox is sodium hypochlorite pic of the label? Could be Na locking out Ca but also looks like Septoria! Stop the sodium hypo and see if it stops progressing and sorry. If you need chlorine and I use it with my clones I use Ca hypo and I drop my Ca/Mg additive.

I just watered tonight, if it was ph, it shouldn't progress. If it does, I'm gonna dump the res, and start it over w/o bleach. I don't really need it, but res has gotten pretty warm lately, and I wanted to prevent a problem, before it could start. Lol

7.1% bleach, many household bleaches are 5-6%. Is the other plant a clone of the affected plant?

Hollatchaboy said:

No, it's a clone from another strain, plus it's in flower, if that makes a difference?

It's not identical DNA so it could simply be more tolerant. Apparently that one plant is your East German judge of nutrients!

Lol yea go figure. Thanks for the advice. I'll probably end up getting the pool shock. I like to keep my res sterile, and it's starting to get warm out, and harder to keep temps down.

Please follow up. I'm curious, I think it's still a chance it's Septoria
