My leaf temp is roughly 73fLeaf temps matter room temls don't... thats the honest truth.
I drop my temls the last week or so of flower to about 70f to preserve terps a but more and pop some color.
Not bad 75-77f is ideal for photosynthesisMy leaf temp is roughly 73f

Heat or light stress? They usually kinda go together but not so much under LED.I've got 2 plants with leaf temps at 77f with the led light 18 inch above but they are showing symptoms of heat stress curling edges thats with temps in tent at 73f

Really spikey or folding like a taco?
Yeah light stress but a few things going on there.... looks like heat but that's likely multiple stresses.Heres some photos.

What are you feeding? And what media?
Have you tested the runoff?
I don't know if its nitrogen or not, the leaves look alot darker in natural light.Yeah light stress but a few things going on there.... looks like heat but that's likely multiple stresses.

Size of pots?
Watering how often and how much?
Phing? What ph down are
Source water? If tap what's the ppm?
That EC is pretty high imo.I don't know if its nitrogen or not, the leaves look alot darker in natural light.
My runoff this morning was.
Ec2.0
Ph 6.4
40ltr pots. Watering once per day 2.5ltr each with 20% runoff.
I use phosphoric acid for ph down. Tap water ppm is 0.09
My intake ec was 2.2 and ph was 6.2
The leafs look a bit darker in natural light.
That EC is pretty high imo.
I think to much cal mag for sure, I'd cut that in half atleast especially in late flower.
How's the airflow? You may want to flush a bit to bring it down just by increasing runoff for a few days and feeding lighter. Like 600ppm for a few days with more runoff then up to about 800ppm and you want to be within about 200ppm with the runoff.
I can't say to much about those nutes or ratios because I'm not all that familiar with them so would have to look them up.
Its is mainly when the lights go out as it need ten degrees drop or they go spindle but when buds are big 28 c is better so buds don't sweat and go mouldyHi all, I've got autos in 4 weeks of flower and have kept my temps at 25 degree c lights on but have come across a few websites saying its best to keep temps lower during flowering 20-23 degree c. Any input would be appreciated. Cheers
If I put the temp to 25c does that mean I drop it to 15c at night. I've only been dropping it about 5-6Its is mainly when the lights go out as it need ten degrees drop or they go spindle but when buds are big 28 c is better so buds don't sweat and go mouldy
18c is as low u should get when lights out lower is ok but slow growth so lights on at 28 c is best in bloom but depends at what stage 28 last two weeks but 32 c is ok that's why use low ec between 1.8 And 2.0 so you don't burn the white hairs and eazy to control from over loaded saltsIf I put the temp to 25c does that mean I drop it to 15c at night. I've only been dropping it about 5-6
