What could be causing the leaf curl?
5 plants, only the middle plant is doing this. It’s also a different strain than the other 4
My first thought was move the light up…
ChilLED Tech 65w in a 2x4 AC infinity tent with the T6 Fan venting tent.
Looking for some insight from a knowledgeable grower
Temps and humidity stay pretty consistent
Yeah her leaves are getting burnt up. If it starts that way too long they’ll be crispy brown.

Plants will sometimes curl like that to hide from the light. It could also be severe pH problems. Do you know your runoff pH?

Which direction of pH swing do you see this? @MidwestGuy
So I’m using the BioCanna line of nutes plus recharge every 7 to 10 days as recommended.
Watered this morning, Ph in at 6.0 and out at 6.5
EC in was around 1700 and EC out varied between each pot.
Media I went with was the recipe Bruce Bugsbee talked about on YouTube 50% peat, 25% perlite, 25% vermiculite. W/ dolomite lime and gypsum Added
@MidwestGuy
Not an expert but my first thought was those numbers are ok,
You are sure you ph meter is calibrated and a quality meter?

Yup, pretty sure. I purchased an Apera Ph20 and EC20 just a couple months back to replace old equipment for my outdoor grow.
I would have purchased the Ph60 but didn’t want the combo unit.
Yep that’s a good one and it keeps it’s calibration well so that parts good
Just wanted to rule out that possibility
Carry on

Looks like light stress to me. I’d raise the light and see if there is improvement.
