What is going on with my SLH (Day 51 Flowering) Pics

What part of the tent are you taking the high temp of 89?

Looks like heat stress to me. Hope a pro can confirm.

By the curling, the plant is getting too much of somthing

I'm guessing your in dirt and this is some major lockout. This could be cause by one of the big two. The first of which is nute burn, the most common one of the two or it a major ph shift, if it in dirt it goes low in hydro it goes high. Did you you just feed it something then this happen? Or did it come on slowly? Lets not forget the dreaded over watering? You get that bear claw drooping too!

There is no particular spot where I get the temp, it just sits in one of the pots and then I check the min/max ever so often. I did just add my cooltube on Monday and before that I was at a consistant 90-94degrees. I water every 2-3 days. It was a gradual occurance, maybe over a two week period till now. And yes I am in soil. My ph meter is currently broken, but before it broke my ph was 5.8-6.3 and I still was getting the yellowing. I have left out Dynagrow for about two weeks, now I'm just using DynaBloom and Protekt, but PPMs are still in the 800-1000 range. Should I add the Grow back?, But it does not look like a Nitrogen deficiency. I think I will flush a second time, just did one about 3 days ago...

My intake is top right, outtake is top left. Using a S&P 150 fan with a 16" circulating fan on the inside.

Change your intake to be pulling air from the bottom, since heat rises the cooler air will pass through the the plants. They way u have it now its just sucking air in through the top, through the cooled hood and out. Not getting to the plants like it should.

Your outside temps(outside the chamber or tent) are a main factor in lowering the heat. If they are 76-80~ going in, then your trying to cool the light with too high temps. Dropping your intake to the bottom hopefully would get you around -5 deg or so.

My first grow i used a 175 cfm inline fan, it wasnt enough to pull through the light and the carbon filter causing my temps to skyrocket. Going with a 6inch 400 cfm fan with a fan speed controller to help keep noise down. Looking at this one -Ebay Fan Link

Only problem is that it is in an outside closet and the temps outside are already in that area. I run my lights at night and temps are usually 80-85.

your plant is eating the leaves( technically P def), its almost time to chop...a feed wil stop the plant from eating itself...but, at 51 days, i would just keep givin it water till chip time...my SLH is typically ready at 8 wks, but it gets super dank from weeks 8-10:hump:

I went ahead and fed with a high p bloom booster (ginormous) after I flushed. I will try to go 9-10 weeks on this one. I don't think blade leaves coming out of cola means re-veg, someone correct me if i'm wrong..Just thought it was genetics.

heat can cause a plant to get all funky leafy lookin like that, dont trip, my room is 80-85f all day, with good air flow its no prob, do you have fans keeping the air moving at all times?

I have an slh recovering from heat stress as well. After I installed another exaust fan and temps stayed in low 80's she is now very happy and pushing out more white hairs. It would have sucked getting a small harvest cause of heat.
