In final week or so of flowering and all the leaves are doing this. Any idea what it is?

autoflower tangerine dream on a 18/6 light schedule

Temp seems fine, idk what’s going on

Nute burn doesnt always happen overnight. Also, your plant is nowhere near being ready to harvest. You got at least another 4 weeks till its ready.

4 weeks would put it at 15-16 weeks for an autoflower that takes 10-12…

idk man; I’m doing research on it and finding it’s something that could be fixed with some calmag and I probably stopped nutes a week early.

First time doing autoflower. So I’m not surprised if I misjudged the final couple weeks of flower; but I just don’t think there’s more than 10-12 days left before 48 hours of dark. I think I flushed early and just messed up my timing. Anywho, thanks for giving me something to consider

Plants are ripe, when they are ripe, not when the description off the breeders website tells you so. Your pic looks like it is only at the halfway point and you still have tons of new pistils, you'll be disappointed if you harvest in 10 days.

Yeah, If it isn’t ready, I won’t cut it. I can tell when they’re ready to cut cuz it isn’t my first grow entirely. My first autoflower grow tho… I just think I misjudged the flowering length. I think the issue I’m seeing is probably from stopping nutes too early and having a cal/mag deficiency because of it… does that sound right? Or is my thinking flawed?

just by reading your op. Your setting up for complete failure bro.
Your plants looks completely stripped of any nutrition and further been locked out from what looks like a ph problem. You have quite a bit of time left. But if it were me. I’d be getting my next grow set up.
Take a few steps back and correct your feeding. Then try to push through till the end. Shouldn to be far gone.

It’s about 75-80 degrees at the top of the canopy, but I can’t do anything to bring it down any further. RH is about 55%

Seems fine, no need to bring it down further from there.
RH is stable during lights off? It really looks like a high heat/low humidity issue. Maybe you're turning your humidifier off during lights out and RH is dropping hard or something like that?

Are any tips curling down as well? If all tips curl up, I wouldn't think nute burn, but if some turn down as well you're probably overfeeding.

Seems pretty evenly spread over the entire plant, was it always this way? Or did it work it's way up or down from the top or bottom?

If nothing else checks out, probably a PH issue

It’s pretty stable throughout the night because I use a dehumidifier to keep it around 55.

tips are only curling up; none are clawing down.

it just started showing about a week ago and it’s not every single leaf, just like 25% of them. Started from the larger fan leaves, but they were yellowing out entirely, so I trimmed them. Maybe I should’ve left them on longer

I have not put them in dark period yet.
I’m using breeders estimate as an estimate for me because I haven’t done an autoflower before. Only photoperiod. So I was using it as a general rule of n

I gave them a flush because my first thought was I feeding too much.
PH problem is possible. Just tested and it came out at 6.3/6.4.

Next grow is already vegging. See below. That’s a photoperiod Girl Scout cookie

planning to correct feeding. Guna just half dose calmag through last few weeks.

I’m still expecting a decent harvest because of the size of the buds. My main concern was why they weren’t fattening up in correlation to the breeders timeline. I wasn’t sure if what issue I’m seeing is causing it to slow down or if it’s actually just that far from harvest

That’s the only time you flush is thru expected overfeeding. I thought you were saying that it was almost time to flush.

never ever give yourself an estimate. It will fuck your head up with false hope. Correct the ph and get yourself back on track. Mark it down for the future. Never worry about it again. You made it this far.

Even then, its better to just do a double feed with the proper EC/PH solution to reset your medium to the proper nutrient level, instead of resetting your medium to zero with plain water.
