Ok, so I watered last night using RO 0ppm water (no nutes, skipped this time). I MADE SURE ph was at 6.4-6.5 on all plant runoff.

I think I'm a little mag deficient (darker veins). But what is causing the twisting?? Could be just too much water? They were SLIGHTLY water starved when I watered last night. Just a water issue?

Also light I'm using is 400w cmh and is 18in from canopy top. been at low 70's - 75F temps

I should mention my PPM runoff was at between 300-500ppm after watering.

Sorry for the lights in pics btw...

maybe its kinda hard to tell from pics...but the leaves are twisted (especially new growth)...and droopy. i know twisted new growth is alot of times heat stress, but temps have been in 70's or in 60's. can cold temps cause twisted leaves? or maybe just water stress??

give it a couple days see if get better?

i know it looks like i'm freaking out lol... but some of the leaves are twisted like in a spiral

Holy shit, it may already be too late!


Seriously why even bother treating this? Yes its calmag and its insanely minimal. That or slight pH issue but you clearly took care of that.

LOL... i was a little bit...

but after the watering the plants looked much worse, and I wanted to make sure it was just recovering from the watering i gave vs a deficiency.

the leaves are still a little twisted but not as bad and they have come back up (not as droopy) now.

how much and often are you watering?

when it gets completely dry... but this last watering i let it go 1 too many days because they looked fine and then the next day they were droopy. So i think it just hadn't recovered yet. they do look better now other than needing some mag or calmag.

Plants look pretty healthy. Yellowing of the bottom low-light leaves is natural and the twisting of the leaves you are describing could be caused by a fan which is blowing directly on the leaves. The leaves lose moisture and will curl to decrease surface area exposed to he airflow. Blow air around your plants, not at them.
