I'm only 2 weeks into 12/12 and this morning I had to prune off a bunch of smaller branches whose tips looked like they were burned and dying although the tops closest to the light all appear healthy.

My first guess would be heat damage, what's the temperature at the canopy?

It's 80 at the canopy... None of the tops on the actual canopy are damaged at all like this. All the ones that looked like this were underneath the main canopy.

Nutrient related then. What are you feeding it, how frequently and do you water with ph'd water in between feedings?

I feed CNS 17 Grow and Bloom 7.5ml of each, neem oil, cal-mag, and hydroguard. I ph to 5.8 every watering which is every other day in coco in 5 gallon buckets.

Yeah was thinking overnuted maybe or some kind of build up. also neem oil maybe? Possibly under-water or bad roots...

I put 1.25ml every watering of neem, I don't foliar feed at all atm. I'll try to take some better pics of the rest of the plant.

Yeah, I read somewhere awhile back that feeding it in a super low dose like this I could avoid fungus gnats which I used to always get with coco but this grow had an 8 week veg with the small amount of neem every watering and still haven't had any bugs. It's my first grow ever using it non-foliar.

Get out the microscope. Looks like broad mite damage to me and the fact you said it’s starting at the bottom branches is another giveaway. look for tiny little clear bugs. With damage that bad they should be easy to spot if it’s them

I would cover the top of the soil 2" with sand, or gnat-repelling material before I introduced neem to the root ball, especially if you are merely preventing.

I'm really hoping that the daily neem feeding is preventing mites... but I just same day ordered a 60x microscope to find out for sure.

also it's worth mentioning that my humidity was extremely high in the tent this past week when my last inline fan went out and i had to wait on a new one. could that possibly have something to do with it too, like maybe some type of mold?

I hope I’m wrong. Let us know what you find when you get your scope. I’ll glady share every bit of advice I have on them if you need it

That's what I thought from the initial photo cuz I've seen them do that, but in the subsequent photos I couldn't see any but if I'm honest the photos still weren't great, need a clear picture from about a foot back shot at the leaves from an angle that lets us see the little white dots, if they're present
