I ended up adding a heater - it's one of those radiator looking ones that heats up oil on the inside. I can run it on Low, Medium or High. High is 1200 Watts. Medium is 600 Watts. I did 24 hours at 1200 Watts and now I keep it on Medium 24/7. I put my exhaust fan/carbon filter on a timer. 15 minutes on, 45 minutes off. Temps now peak at 75 degrees when lights are on and bottom out at 68 when lights are off. Pretty sweet considering my basement temps are now 57 degrees.You could orca/poly some of the open sections to seal some heat in. Help the heat rise that 10 degrees. You could throw the panels on the base pointing upward to light lower branches.
I was just going through a similar situation. You might enjoy this, sure it’s nothing you haven’t been over before.

Dang bro, killin it. Looks great.Day 119
Flowering - Day 40
Cruising right along. Rez change tomorrow - I'm still running her too hot. Starting to get some really beautiful orange pistils! Flowers are a bit small but definitely nice and sticky.

With the 315W CMH on top, canopy top is 7 degrees higher than ambient. With the 600, it was more like 10. The top row of LED's are obviously contributing to this as well.Glad you were able to figure out what's going on Hot. I'm sure you will have her back on track in no time! I still think she's beautiful & never mind a weed, She's a BBB! (Big Beautiful Bush)
When you have a moment,
out of curiosity & to possibly learn something. What are the temps & Rh of your canopy as opposed to your ambient temp & Rh?
Thanks in advance for answering my question.
Have a great day!
Quick update - Canopy temp is plus 7 degrees and minus 9% RH.Glad you were able to figure out what's going on Hot. I'm sure you will have her back on track in no time! I still think she's beautiful & never mind a weed, She's a BBB! (Big Beautiful Bush)

Looking good! They will swell agreed on the foliation!Day 122

Found some more problems this evening...ugh.
Canopy temps have been substantially higher than ambient room temps despite having lots of air movement. The top 20% of the plant is experiencing heat stress. I misdiagnosed this with over-feeding.
Here is what I did and what the plan moving forward is:
The grow room temps are going to drop which is going to cause the RH to rise so I'm putting my basement dehumidifier on a timer to only run during the light-off cycle.
- I removed the 600W HPS on top and put in a 315W CMH
- I'm only going to run my heater during the lights-off cycle
- Going to order a 3rd oscillating fan
Regarding the nutrient overload, I'll just continue to hold the course - 0.6 EC with CalMag accounting for roughly 50% of that.
I'm also beginning my last round of defoliation and will spread it out over the next 4 or 5 days. I will be fairly heavy handed.

Thanks! Hoping to finish strongLooking great Diggity, excited to see the outcome!

Flowering - Day 45
Slowly working thru and solving the issues that I've had. I've got the feeding regiment back on schedule after a 5 day detox period. Fresh rez change today.
I also have the room temp and canopy temps under control now. I'm increasing my ambient room RH 10 points.
Ambient temps: 70 F
Ambient RH: Between 55% and 65% depending on temps.
Canopy temps: 75 F
RH at the Canopy tends to be around 10 points less. This is subject to change as I monitor things.
315W CMH up on top and that will probably remain for the rest of the grow. I kind of wanted to see how a CMH performs anyway.

Yeah that cmh should be a great Finisher. I been considering uv bulbs during late bloom myselfThat CMH will frost them up for sure. They are great lights.
Looking good.
Good question. I now think it is the strain. It first showed up in Veg when I got a minor russet mite problem. It showed up again during flower when the weather changed and got really cold - it took me a few days to bring on a heater and get my temps dialed in.Just curious... Are those purple stems strain or PH issues?
