FC3000 Causing Issues at only 30 DLI. What’s going on?

So at this point I’d say I’m about 1 into flower so I’ll target a bit warmer and bump the humidity a little as well.

However the big question is why is one plant freaking out from the light while the other is fine?

Just chalk it up to genetics I take it? This FC3000 is way different than the TS1000 I was running before.

Its not the light, its their food. Overfed, too much P, causing skinny new growth leaves that dont flatten out.
Recovery will be slower with dry amendments.

Ideally in this situation, they would get a balanced feed with everything available (i.e. liquid). Floranova Bloom never let me down.
Best of luck to you.

How much H2O2 were you using? I get pink slime In my ultrasonic humidifier and added 30ml/gallon a couple days ago.

I think I read that H2O2 is benificial but couldn't find any info the concentration to use.

H2O2 in a humidifier? Never again.

I started doing that for my grow this spring and, after a while, realized that I was putting a lot of H2O2 in the water and that was being sprayed…on my plant. I refer to it as my "Claus von Bulow grow" (if that rings a bell).

I sincerely believe that it stunted the growth of the plant, hence the "never again" comment. It may be that H2O2 can't harm a plant but I can't point to any other causal factor.

My plants are topped and LST'd and are vegged under a veg LED so they're "a shrubbery" typically. In this case, it was more of a wreath than a shrubbery.

Previous grow (no H2O2)

Lot's of nutrients can stunt a plant as well, but I still use them. I appreciate your decision to stop using H2O2, but I'd like to explore it. I've used 15-30ml/gallon without any apparent issue, hence my question about the concentration you used.

Thanks for the reply.

I don't know the concentration. I was just "adding a little" to stop the algae and I ended up adding to many "a little". As best I can tell, ended up causing an issue.

Thinking back on it, 20 or 30 ml in a gallon, perhaps.

"It's not the poison, it's the dose" - very true. I'm once bitten, twice shy on this. If there's a metric on the safe dosage, I'm happy to revisit it because it does cut down on labor. I just don't want to pooch another plant.
