What is this on my fan leaf?

[Shinobi cm]

Hey guys -

I had a pretty big issue with nutrient burn on my OG Kush Auto (1/2 Tiger Bloom). Had almost all of my leaf tips browning and curling up.

A few weeks later some of the leaves look like this. Is this just the result of more nutrient burn or is this some sort of disease?

Completely indoor grow, tent was cleaned before placing the plants in there.

Everyone is going to need more info and a full plant pic to even start guessing.

Here are some various pictures. Grown in Happy Frog soil, temp. around 73 F, humidity between 50-65% (keep a small dehumidifier in there but doesn't seem able to keep up after the plant is watered and humidity rises. SF1000 light, was using 1/8 strength, then 1/4, then 1/2 strength Tiger Bloom when browning of tips started.

How often are you feeding watering? @Wizzlebiz uses that he would be more help than me

They are in 3gal pots so every 4 to 5 days has seemed about right. Nutrients only every other watering. Just recently started to pH my water. They are week 9 since seedling sprouted by the way.

That looks like it's really hungry for some N.

Off subject what’s the red thing you have used on the supper cropped branch please?

I'm stumped on what to do. It is close to harvest, I'd say less than two weeks. And my tips continue to brown and curl like they are burned so I'm not sure if I should add a small dose of nutes or not.

Urine is an organic natural source and immediately available form of N.

Low stress training clips from Amazon, Engineered Essentials is the brand

Not a disease. Looks to me you used too much tiger bloom and locked out other nutrients as a side effect.

Just water for 2 cycles and then get back to lower levels of tiger bloom.

You are going to also want to add a bit of grow big to the mix. You are nitrogen deficient

@Wattzzup
I switched to Dr earth. I'm never going back to nuke nutes.

Thank you! And same over here.

My plan for next time is to go straight Ocean Forest and pH'd water until pre-flower and then one feeding of Dr. Earth Flower Girl. Outside of that just monitoring for deficiencies. Definitely learned from this mistake.
