HELP! Not sure what is happening

[Euroaznscotty]

Hey guys,

noticed last night some leaves were changing now entire stems look like their dying... Not sure the issue.
i water every 3 days. PH was a bit off rectified that. I cant move them unfortunately. The lowest stems are effected the most.
at day 53 flower

Looks like a Magnesium def at first glance. I would ride it out with the corrected ph and see if that fixes the problem. The ph being off is a very common cause for problems.

 

[Euroaznscotty]

Alright. Ill give it a go, just worried because I estimate 3 more weeks for flower and at this rate it'll be dead in a week

 

[Agentbuckwold3]

Just try not to do to much "fixing" at once. She is already stressed and trying to change to many things at once will only hurt her more. What medium are you growing in?

 

[Flockshot]

My guess would be Potassium deficiency this late in the grow, but it actually looks more like light burn. HOWEVER, if your ph has been off (I assume too low) that is the most likely candidate.

Flush if in coco.

 

[Agentbuckwold3]

Agreed if Coco do a flush if the ph fix doesn't solve the problem.

 

[Euroaznscotty]

I'm growing in soil. The problems didn't start showing till yesterday.
i did raise my light up 4 inches yesterday. My first thought was light burn and wind burn.

 

[Dutchman1]

Ya, I was thinking they look burned or dried out. Heat,light or water. What light and how close?

 

[Euroaznscotty]

1000w hps at 10 inches

 

[Agentbuckwold3]

Shew that's a monster. I would say it's a safe bet that had something to do with the crispier leaves.

1000w hps at 10 inches

That's a toaster oven. I have a 315 CMH at 22-28 inches.

 

[Euroaznscotty]

Its backed off now, it is a 1000w hps air cooled. I don't get any "back of hand test" heat at 4 inches. 4 inches its warm but not uncomfortable

 

[D.A.A.S.69]

Sure looks like heat to me , but have you checked for bugs real, real close, they can kill a plant in a day or two.

 

[Euroaznscotty]

I have checked for bugs with a loupe. None that I could see. I'm thinking light and heat stress combined with off PH. Backed the light off to 20 inches, and stopped the fan from going over them.

will give it a couple days

 

[Mr.furley]

My 600 hps is at 18" and sometimes it seems to close.

 

[D.A.A.S.69]

I agree with MrFurley, and I'm also glad it ain't bugs, I bet she does much better with your adjustments. Good Luck with her.

 

[Euroaznscotty]

Thanks all. Bit of a surprise this morning when I saw it, especially with those buds themselves drooping

 

[Dutchman1]

10 inches is waaaay to close for a 1000 watt hps for most strains with no co2. It doesnt matter if its air cooled or not. That damage doesnt happen overnight from Nutrient deficiency. thats why I said heat , light, water. Here's a chart to help with distances.

 

[Mr.furley]

Agreed Dutchman, during my last stretch The 600w was only 12" away sometime, as soon as the stretch ended around week 5 and my buds started fattening up my top colas start to grow sideways to Xscape all the lux ( was reading 100k ) and I moved my light to 18". All that and it's a air cooled with glass that diffuse the Lux can't imagine the par of an open thousand watt withing 10".

 

[Dutchman1]

Mr Furley, do you find you often need to raise your lights later in flower? I have had to do that twice now and wasnt expecting it. I thought you just kinda just kept sneaking them down in flower.
