Death Destruction Death

title is a bit dramatic. sorry team. First time grower w a lot of variables, but I've searched high and low and can't find any photos like my plants. I want/hope it's a K issue, but I have no clue.

Here's what I know:
-Plants are afghan autos
- week or so into flowering
-plants are 60cm tall
-no nutes
-grown outdoors
- 5gal pots
-watering every 3-4days or whenever dry (i've used tap water until recently, but i drink it and don't crap my pants so i assumed it was alright for the plants-- i've switched to bottled water as of 2 waterings ago)

I have no clue about the soil, I bought it from a bud grow shop in unmarked bags...lol, here's what i think is the composition: White peat, black peat, perlite, worm castings. 1.8 kg / m3 mineral NPK fertilizer (12-14-24). ***google translated the composition from the only soil mix the sell online which is what i hope htey sold me***

Effected areas are mid range fan leaves. Some older or newer, but new growth doesn't display problems. If it's a simple problem, phew; however, I live in South America and don't speak Spanish. In other words, finding and communicating exactly what I need is difficult. I just wanted to be 100% sure of the problem before going on an epic adventure in search of a cure to save my precious hijas.

What does everyone think?

Please let me know if you have any questions. thanks again everyone.

looks like you got nutes on the leaves. when you water dont pour it on the plant it will burn the leaves

Thanks mike for the input. I have a dozen more seedlings ready to be transplanted, and I will be using nutes for those so I'll keep clear of the leaves. The plants/photos above I am NOT using any nutes so do you think it's just water burning somehow? /panic

Should I remove the infected leaves/whole dan leaf or let it ride?

Do you thik he just poured the nutes on the tips of the leaves or something?

Thats common if you water with a larger container sometimes the leaves get inside the watering container. happens to me sometimes when i cant see anything lol

It was probably some water dew on the leaves that cooked in the sun. no biggie. Get the dew off your leaves in the mornin

Thanks everyone for the info. I keep telling myself not to fuss over the plants, but i guess I have that first time grower bug and continuously wonder the following: how come they're not 20ft tall already, what's that single spot on a leaf, should I be sleeping next to time in case they cry out for help?????? lol...

Again, big thanks guys&ladies for the needed confidence boost. I'll definitely post a their glamor shots once ready

You have to have a huge pot to put them in and then they will get huge.

i use 20 gal pots i get a good 6.5-7 ft

I've been reading incessantly and I'm leaning towards a phosphorous deficiency whether it's due to a PH imbalance with my aforementioned poor watering practices or just having hungry plants with zero nutes.

Does that look about right?

Also, 20gal containers... /drool. I'll certainly try that after I get two grows under my belt haha. Thanks again everyone

You should be feeding anyways .....cannabis is a heavy eater. This is why I think its just dew burn: The rest of the leaf is pretty much flawless. If deficiency, the whole leaf would be discolored in this case.

Big Texan and Diabolical666 answered you. It's magnification from drops of water creating a thermal burn, ever burn ants with a magnifying glass? Same principle.

No I think it was that rare and hardly seen phenomenon known as splashing and if you look at the other leaves you will see they are pristine. Actually very nice looking plants. That's how you can tell it was simple splashing.

Thank you curious2garden, Big Texan and Diabolical666, and I appreciate the compliments regarding their healthiness; however, it's all Mother Nature

You guys won't hear from me regarding this issue again.. Post harvest I will post some *hopefully* gorgeous pics as payment for all your help.
