What causes my plant to look like this?

Looks like some major issues in the medium from overwatering and some PH fluctuations. Flushing is a great tool when needed but I feel it was overused and the roots got fucked from it. Your diary says your growing in canna coir mixed with perlite but on another week it says its soil??, Typically coir need a PH value of 5.8-5.9 and then can let it get up to 6.1-6.2 in flower. Some will say its impossible to overwater coir but I have found that not to be true and quite possible. Coir is also void of any nutrients and they need to be feed from day one if you are using it as the medium. Also in your germination week it says your using a TS1000 and HS40... what is HS40?? I also read you are not using an extractor fan as you can not afford it at the moment, best to leave the tent open with a fan pointed into it to help with air circulation. I think all the damage has been done and there is no easy way to fix this. Get a TDS pen and start monitoring your EC/PPM of the feeding solution when using liquid nutrients and avoid flushing as much as you can. only use it when its needed from excess salt buildup. Take all this new information into your next grow and it should work out a bit better. Good Luck! === Seems I have a fake troll account trying to cause shit by emulating me. They even went as far as to copy my profile picture and response to there troll lol. Someone sure is but hurt. m"Q"use is not @m0use Q vs 0.

I have a comparable setup. HS40 tent and a high-power LED that I never run at >50%... so I use 50W including (high efficiency computer) fans. Right now I am researching a micro de-humidifier - but the one you seem to have in your small tent might be overpowered. I am running at 70% humidity right now because I let my fem. MauiWaui grow too big in veg. but it is not a problem if you have proper ventilation. For our tent I recommend multiple small usb powered computer fans. Maybe ditch the de-/humidifier.

Looks like it's suffering from not stretching for light enough, maybe it's too near. I wouldn't listen to the other mug answers as they are bullshitting you. ***disclaimer, multiple dumb people are answering all questions as there is a contest called GOTM, when a user is selected as the answer they get a point. So hand it over to me, I'm the best at typing lots of crap out and screwing people's grows up, in my fact, me and my buddies real disclaimer is, oh sorry theres more tgan one answer for everything and why believe a random idiot who has FA better to do.

High Faegrows, First of all put the dehumidifier outside the tent. The plants transpirate the same amount of water that you give them into the air. It is impossible to catch all this moist. You better make sure that your inlet is sucking dry air into the tent instead of reusing the moist air. And the leaves look really dry, is it too hot in your tent? It is possible that she transpirate faster then she is able to refill the moist inside the leaves. When this is not the case it could be a deficiency due nutrient lockout or pH issues. You can measure the pH from your soil to make sure that this is not the cause. I will explain how to do this. And if the pH is in the right range then you need to flush your soil so you can start giving the right amount of nutrients again after the flushing. I will explain you how to flush the soil after I explained you how to measure pH in soil. To measure pH in soil, just follow these steps. Your pH should be around 6.2. 1. Place soil sample about ¾ full in sample jar and add distilled water to cover soil. 2. Cap the jar and shake the soil vigorously a few times. 3. Let mixture stand 10 minutes to dissolve the salts in the soil. 4. Place the pH tester into the wet soil slurry. 5. Measure pH and record measurement. If the pH is in the right range then flush out the nutrients with a good flush of your soil. For this flush just follow these steps: You can do this flushing by slowly pour water pH 6.2 onto the top of the soil, allowing it to drain freely from the bottom of the pot. Pour slowly, so the water doesn't overflow from the top of the pot. Use approximately four times the pot's volume in water to flush the soil. For example, use 1 gallon of water for a 1 quart pot. After the flushing you need to let the soil (almost) dry out completely. From there you can start giving water with pH 6.2 and nutrients but do not exceed EC 1.5 Goodluck!

Oh man, that is pretty weird.... the small new growth had me first thinking about a potassium toxicity - but not quite... and the variegation of the leaves doesn't match up either... Unfortunately, I think what you've got here is the mosaic virus even though there's zero scientific evidence that cannabis can be infected by it.... it has all the symptoms. If I were you, I would read this article on it and decide whether or not you want to follow their recommendations about what to do now... https://2fast4buds.com/news/tobacco-mosaic-virus-in-cannabis-plants-symptoms-and-prevention Good luck... going to follow this grow to see what you decide... damn!
