Help, wrinkled leaves on thriving plants!

Growlog link: [paste your link here]

If you don’t have a growlog please answer these questions.
What strain are you growing? Is it Auto, Fem or Reg?
Are you growing Indoor or outdoor?
Are you using nutrients? Which ones? How much? Can someone help me get my growlog visible so I can get some help with diagnosis of 2 plant’s. They have very weird wrinkling leaves on maybe 20% of the plants and cant seem to fix the issue

Heat stress maybe? how far are the lights?

That’s possible, I did have a heat issue but that was about 4 weeks ago. It got up to 98° for 5 or 6 days during the day and then I bought a evapotive ac and got it back down between 75-85° (not perfect but the best I can achive where I have my grow room) the light is a 1,000 watt led and its 26 inches away right now, it was 30 inches away before I switched to flower 5 days ago. My grow room hasn’t seen more than 85 degrees in 4 weeks, but it has been getting down to 60 degrees at night.

In bloom setting. The heat intesifies, you should try raising up instead and try to remove anything blocking primary bud sites. Try raising it up past 30 and see how the new growths do

Thank you, ill move it up as soon as I get home and update in a day or two

looks like some type of nutrient deficiency. What water are you using? And are you using nutrients?

I ph my water to 6.0 and I’m using fox farm grow big veg state nutes at half recommended dosage and occasional super thrive folair spray, I just gave them the last veg state nutes watering and next up is black magic flowering nutes

You are locking out nutrients at 6.0 (calcium & Phosphorus). You should be at 6.5 or 6.6. This chart is from Oaksterdam University

I would also add that the temperature swing is going to stress them. Nothing biologically is happening at 60 degrees and stomata close at 83, which is evidence of heat stress. Try to maintain the temperatures between 75-80 at all times.

Ok, I never thought about the fluctuation of temp would affect them when its too low, thank you. You’ve been very helpful. Hopefully I see a major change in the next few days!

I Just gave them a folair feed before lights go out, I’ve been doing folair feeds 1 minute before lights out every night for 4 days , just water and some super thrive and it also seems to be working well, whats your take on folair feeding with water/super thrive daily? All the new growth seem to be very happy and lush so far

Foliar feeding is fine. They look good in this photo. If it seems to be working keep doing it. What nutrients are in the foliar?
