Dry, inward curling leaves

Hi all, sorry for the spam but my diesel leaves near the top are curling inwards, and it's nearly ready to harvest. I'm what's causing it? 

 

Research suggests light burn, nute burn, too hot, too cold, over watering... :wallbash:

 

Any help would be great! 

 

Temps range from 21 lights off to 28 lights on (canopy). Rh sits about 50, not much higher. 

 

I could stand to turn down the nutes a little, have backed off the ec (really hard to get my a+b below 1.4). Last few feeds I'm doing 0.9 explode and multi total. 

 

pH might have snuck up when I let my big bucket sit for a week.

It's worse! Not sure if this is related, please help! I don't think it's bud rot, humidity got down to 40 today. 

 

I didn't water yesterday, thought I may have been over doing it, then this happened...

 

This is only on two buds on one plant (of four). Of note, the plants have a really green smell, like dry leaves. Not a pongy, dank smell we all know and love.

Can't raise the light, but I have turned it down from 600W to 400. Bad for the light, but at this stage I don't mind!

I have two younger plants, one being in the latest photos. 

 

Also, you're welcome to give constructive feedback, but if you're just gonna be a smart arse, then do it elsewhere. :thumbdown:

Crap. It's bud rot. Pulled it apart and it was brown down to the stalk. Ffs. 

 

Have chopped and hopefully nipped it in the bud, but understand that it's likely on other buds. Dehumidifier on fully now. 

 

Fuck.

Rot is never good. 

Do you have fresh air going into and around your tent? Your profile says "no fresh air". You need to change the air in your tent as mold spores will be filling the air. Check the fan/s you have moving air around the tent. Make sure it moves air over the buds

I could certainly have more fresh air. As its cold, I've not been leaving the door open as much, but I've now got a bigger heater out there so will ensure I do. Dehumidifier is wiring overtime now as well.

The plants were suffering from light stress for quite a while. This is enough to cause bud rot. I've done it myself so I know what I'm talking about. It's very disheartening.

- Do what you can to raise the lights in any way possible.

- Keep the lights turned down to at max 400 and maybe even a bit lower (I don't know the size of your gro'om).

- Make sure you keep the ventilation going. It only has to ruffle the tops of the plants slightly.

- Use LST to keep your plants nice and low.

Good luck
