ya need a coco grower here,,
need to know what flower nutes?
how much used?
what ph?
what light and how far from canopy?,..

I grow in organic wonder soil ie. Living Coco coir thats loaded with nutes.

Anyway most definitely thats a sativa plant long skinny cool fingers.

Whattca growing? ie. OG Kush
How many days ?
Outside/inside?
Pot size?

U flush with rain water, why, did you check the ph, how much water
New growth turning yellow, ur ph is to high or to low .

PH tap water to 6.5 ph, get your 15% runoff and check ph ppm and ec, this info is needed first.

Hi
Gorillakzittle strain
Used rainwater as on water tanks here in Western Australia
Rotated daily from sunshine 10 hrs then inside hps lights 6
Lights about 1foot above plants
Now outside getting 12 hours sunlight using flowering additive it is autumn here but days are average 28 degrees Celsius
Flushed until water flowing freely from drain holes
Shall check runoff after next flush but am thinking probably to late to save?
Rain water ph 6.5
Adjusted when added nutrients to get correct ph
Appreciate your advise

Good day if your doing straight coco and perlite. Please drop ph down to 5.8. If your using nutes designed for coco ok but if not be sure to add calmag 1ml per liter of nutes. No need to flush with rain water unless you overfeed. Water with quarter strength nuts 20 percent runoff. If she responds well you will see healthy new growth. Nothing fast and dramatic take your time adjust nutes allow for 72 hours to make adjustments while monitoring plant. You can also make a calmag spray and apply to leaves at lights off make sure its ph 5.8. Your sweet spot in coco is 5.8 to 6.2 late flower. Keep it there and your golden. All my grows are coco and perlite with liquid nutes

I tried coco one summer and killed 2 grows , with underwatering and overfeeding and salt build up, if you dont know quite what you are doing i would recommend soil....i would also not put the plant in the sun then under leds for 6 hrs, its a totally different type of light and could stress the plant as its constantly having to adjust.
That looks to me like potassium lockout . yellowing down the edges of the leaves,. magnesium , calcium and potassium compete for space on the roots , so if you have given too much cal mag it might have nudged the potassium out the way.? it doesnt look like you are short of nitrogen.
I dont know how to correct in coco really but dont forget while you are sorting out the rootzone , (like flushing with plain water , or i think you can buy something called recharge ) you can always give it a foliar feed , foliar feeding takes in less than roots but it is instant .

Agreed with carrlosescabar its saying please feed me you flushed all my food away.

Coco guy here. Looks to me like mite damage not nutrition but better pics would help. If they were outside like you said you need to get a microscope at least 60 to 100× (a jeweler loupe will not work) and check for broad and russet mites asap. They attack upper/top growth and their saliva is poisonous so you get that shriveled taco look.

If it's clear of pests I would be looking at pH and micronutrient lockout. When issues appear first on the top of the plant they tent to point to a few specific things.

talking of pests , i have a gorillazkittles at the moment which has been indoors since day one , about 3 months now and couple of nights ago i noticed an infestation of baby aphids. no idea how they got in there, i can only think they were in the soil somehow..luckily they were only on 4-5 leaves so i could take the whole leaf off.
I killed one of my grows by adding too much PK14/15 in bud, it had slight leaf tip burn (because i didnt flush enough) then i added the pk and it instantly tipped it over, and the leaves curled up...how much bloom nutrient did you add?
my leaves seem broader than dogsbreath ones..
