When I opened this thread and saw the plants I was looking forward to the comments other growers would have about the plants. I am running the Gavita 1650 LED. I am told they are the same at the 1700, but I have not verified the specifications. Regardless, I have seen the exact same thing. In my experience it is the lights, specifically the led's. I run both the gravitas and grows choice RIO-680's or something. They both can do this to a plant.
Yes that is what I meant by running them at 65 percent. My controller allows me to increase the watts to the lights by a percentage. You definitely need some N but lets see what the Pros have to say.Hey Anthem,
Appreciate the response I also think it’s the strength I’m running the leds at as well.
That white dust is just some drywall particle that fell when the lights were getting switched around.
More CSI: Miami in regards to nutes etc. The only thing that is solid or "concrete" in regards to both of OP's threads is "pests". I don't even want to comment on dietary needs until he gets his bug problem under control.What's your growing medium again? Coco? Soil? What's your water like out of the tap? Do you use RO or tap water?
Burnt tips and claws are only 1 sign of nutrient toxicity usually nitrogen but different nutrient toxicities will show different symptoms. This is just a swing in the dark but sort of looks like a calcium toxicity problem from the information you've given so far. Depending on your medium and water you may not need much if any calmag.. I really doubt lights are causing this problem, though.

Broad mites and the like are the holy mother of evil in regards to cannabis. The shit the guys are trying to sell you at your local spot won't work, and most have never taken the time to study broads to make a good recommendation on treatment.Bugs are a bitch. I see more spider mites being posted on here than I have ever seen in my life :D
I shoDon you have a lux reader? I bet if you measured the gativa lights, it would come back too high.
I have had same looking problem without bugs, so while they maybe present something else is also going on.Since you absolutely refuse to use a scope, here's my thoughts....
That pyrethrin you sprayed in your other grow is only meant as a knockdown, and if you don't take the time to thoroughly and evenly spray your medium and the undersides of your fan leaves, it won't be as effective.
Your typical spider mite, and most herbivores that are common to cannabis have the ability to process their own diet, they take a bite, and move to the next site.
Your broad/cyclamen/russet mite (micro mites) use completely different mechanisms to feed.
They cannot process their meal without the use pathogens. They attach themselves to their feeding sites injecting those sites. These pathogens suppress JA/SA/ABA pathways, these pathways are your plants "defense" mechanisms.
That Avid you used promotes ABA functions, your micro mite's primary feeding mechanisms defeat those functions which is why your problem won't go away in your other room.
With all those pathways suppressed, your plant will continue to struggle from a "hormonal" standpoint, and refuse to feed.
I've provided you with plenty of advice in your other thread, I shall now leave you to your ways.
