Good evening everyone.

Its now week 7ish of my autoflower (I got 3 more plants that are younger, and 1 that is the same age but still in growing phase even though its the same genetics etc)

I didn't check the back of my plant for like 6 days, i was gone for 3 and the other 3 i forgot.

Today after feeding/watering i turned the pot around, and found these leaves with really weird spots and discoloration.
I tried searching on google and on the forum, but It can be alot of different problems with different solutions. So before trying something myself. I wanna ask you guys what you think about it.

I appreciate all the help and hope yall have a great day.

Would help if you could list your feeding regiment/schedule, medium, and environment. Sometimes when your pots get really dry or really wet, you'll start to see lockouts or deficiencies.

exactly ... also the leaves alone are not enough for an accurate diagnosis. We need a few full plant pictures ... some from above the plant and some from the side. You're trying to capture the whole plant profile in these pictures. We'll also need to know your feed routine.

To me, based on just those pictures, my guess (just a guess without more information) would be wet feet/improper watering.

Alright.

I use Terra aquatica feed, its a starter it with grow, bloom and finish nutrients. (See picture) For my medium I have used Canna terra proffesional, mixed with perlite and some seeweed.

My enviroment is pretty bad right now. Its summer, but the weather changes quite a bit every day. (Next 7 days will be rainy with 23 degrees celcius)
Humidity is always above 75-80%. The sun gets through most of the day (they get like 12 hours of direct sunlight on a perfect day) And then indirect light till night falls.

I dont really have a feeding schedule. I follow the aquatica feed schedule but I cut the ML's in half since i grow autos and they mostly advice for photos.
When I feed/water my plants really depends. If the weather is shit (Like today and the next few days) My growing pot can take a week to dry out before I think its okay to water again (The soil just doesnt dry out and the pot feels very heavy) And the other week the pot dries out in 2/3 days because temps shoot up to 30 degrees celcius.

I have done lst on my plant, and removed some leaves (Some with discoloration and rust spots, and some because they were blocking budsites from getting the sunlight they needed.

If you're using Terra Aquatica you must be in Europe. It's rebranded GH Flora series and it's new name is part of the spin-off with GH-Europe deal. It's a great product when used as directed based on the feed charts. I'm in the US, I use the product regularly as my go-to nutrient regimen. The only difference is the Terra Aquatica feed charts are a bit different. It's supposed to more closely align with the mineral content of typical European water supplies.

Those leaves are showing the issues they are most likely due to watering a bit too frequently. Give your plants an extra 12-24 hrs between watering. Water thoroughly every watering. Ideally, your plants should be asking for water every 3-4 days but if your soil mix retains too much moisture, this interval could be longer.

Yes, I live in the beautifull europe Northwest region.

I always wait with watering till the first 1-2 inches of soil are dry, and I can also feel the weight of the pot by picking it up (It weighs almost nothing when I go to water) And I PH my water ofcourse after adding the nutrients.

But like i said, sometimes the pots take a week to fully dry out and sometimes they dry out in 3-4 days. I think happens because of the weather that has some moodswitches here in europe.

Like today the pot was completely dry and I gave her about 2.7 liters (0.7 gallons) of water. I watered slowly over a time of about 2-3 minutes. I add like 500ml and wait for it to settle, and then add 500ml more etc etc.

Ill just cut back on the watering for now by waiting another day just to be sure.

I do have another question tho.

I have another plant (5 total, but the other 3 are different strains) the one im talking about is the exact same seed, same genetics, same sprout day, same watering same weather conditions and is also a autoflower on week 7. But unlike the girl in the picture, the other one is still growing and hasn't began producing bud yet. I dont think its normal for an auto to grow for 7 weeks right? Normally it would be around 4-5 weeks.
I have 2 other plants that are 2.5 weeks younger, and they are starting to grow pistols, while the 7 week old one is just still growing leaves and branches. Is that normal? or is there a chance that my 'autoflower' is really a photoperiod that got switched out?

I really appreciate your help!

It's hard to say about the other autoflower on week 7. It could still be an autoflower and simply be a different pheno from the other. It's also possible a mistake was made by the seed source. It has been known to happen. If it goes too long, switch its light cycle to 12/12 and if it flowers, you have your answer. Likewise, it will flower outdoors on its own once your light cycle gets below 14 hrs a day.

I will just give it 2-3 weeks more and if it still grows, ill switch to 12/12 by giving it darkness myself.

I cant wait for the days to get shorther because that means in my country it will go back to raining almost daily and low temps. When it rains im not comfortable leaving my plants in the rain so i put them under something in my backyard. Which means they dont get direct sunlight anymore. I guess that also affects the growth of my plants

I'm in Michigan. Wet falls start early here ... It's early September we start seeing night time temperatures hitting the dew point. That is when problems with outdoor cannabis begins. It sounds like your weather can be similar. Wet/Cloudy/Frequently Rainy weather, cool damp nights .... If this is the case, consider introducing your 7 week auto to an early bedtime now so it has time to finish before the worst of the fall weather occurs.

Very possible bro, I’ve gotten photos in my autos pack before.

Yeah its exactly like that weather. But right now its summer, and the weather is also shit. Very high humidity, most of the days see some rain, alot of clouds, so the problems are already here xD.

I will start tomorrow by giving it 12/12 and see what it does. But how do I calculate the 12 hours light? Does that mean just any light? Indirect/direct? Is that from the first sunshine at 06:00 in the morning till 18;00 in the evening? Or does the 12 hours start when my plant gets direct sunlight, so no shade or clouds?

 

[LoveGrowingIt]

I didn't check the back of my plant for like 6 days, i was gone for 3 and the other 3 i forgot.

Today after feeding/watering i turned the pot around, and found these leaves with really weird spots and discoloration.

I'm wondering if the leaves with the spots were facing a wall.

 

[dmigch]

Very possible bro, I’ve gotten photos in my autos pack before.

Would be cool tho, this is my second grow (Ive done one 4yrs ago) And I have never touched a photoperiod before. Mostly cause the green stuff is legal to have, but illegal to grow here, so i can't have a big bushy ass tree in my backyard.

 

[dmigch]

I'm wondering if the leaves with the spots were facing a wall.

They have been facing a plastic storagebox when I put them under my canopy to shade them from the rain, could that be the problem?

My other plants didnt face that box, since I had enough room for them to spread. And they dont have those weird leaves

Tbh bro you should be good the grow season is whiny down, just trim her up and tie her down. Good experience for next season

light is light. There's a threshold but you would be better off tossing it in a garage or a shed over trying to figure out the exact theshold.

That's quite possible.

 

[dmigch]

And to add some more info, some of the leaves showed some rustlike spots, I tried searching

Alright I will try that. I asked because maybe it needs a certain amount of PAR to call it a good 'level' of light intensness.
And when I leave her in my backyard she always gets some light from the moon, and streetlights that are on. So theres always some light. Ill put her in my small barn every night from tomorrow on

Over-all your plants look fine from the pictures you shared. They don't appear overly stretched like they have been suffering from inadequate light. So how much light they are getting doesn't appear to be an issue. Those leaf spots we spoke of earlier could be due to a more humid/low light micro-climate like the side of the plastic storage container like @LoveGrowingIt said. All things suggest you're actually doing pretty well. The biggest issue appears to be the auto that has not shown signs of being an auto-flower.

Edit: Consider larger non-plastic fabric pots for next year. A 5 gallon fabric pot with a quick draining soil mix should give you slightly larger/better yielding autos for your next year's summer cannabis run. I think you have done an excellent job with what you've used.
