----------------------------------------SPECS:
This is my 3rd time growing and I've had no issues in the past at all with all the same soil, lighting, temp, and humdity. Everything is controlled on thermostats and inkbird humidty monitors. Doesn't get above 45 hum 26-27 temp.

Cal mag every few weeks and greenplanet nutes (I under feed abit just to be on the safe side) every week.


1000w leds for 10 plants. Heat of light never been a issue.. Wattage tested correct by multimeter (electricity prices are insane in Australia so can't use lights that use to much power.).

Growing in soil. SATIVA AUTOS blue amnesia XL - 3-4 months old.

QUESTION :20210113_151125.jpg

Now, to the topic at hand.. I was told I had a potassium deficiency, so I brought potash but it didn't make a difference. Bottom of my plants are yellow and have yellow dead leaves and it's growing upwards fast.

The top leaves are crawled inwards and leaves at the very top near the buds are spotted yellow.

I tried flushing awfew weeks ago and nothing changed. Plants continued to get worse. I tried a small amount of potassium, and they got even worse again.

I was told to uproot them and throw them away at this point. But my plants are very far along so I don't want to just uproot them when they have such nice buds on them.

The trichomes are all white when I looked 2 weeks ago.

What should I do?

Looks to me like you have some nute burn on tips but brown spotting looks like calcium Def. I would do a flush with cal/mag. Some leaves look like they are clawing from too much nitrogen.

That thing is heat stressed to shit.

What looks like revegging on that auto is a product of high temps.

Between the foxtailing and the single blade leaves major heat stress. Probably to much nitrogen at some point of flower as well.

Definitely nute burned as well.

With all of that said. It still has weeks to got before done. And yes it can finish.

Temps are normal. All set on thermostats. Never had a issue until 3 weeks ago. 26 degrees and nothing above 45 humidity
