Leaf kinda canoeing down on one plant with dark leaf

[Tipistroy]

Hi everyone, I’m gonna start with a description of what I have

Strain - badazz cheese from seedsman
# of Plants - 4 (different strain)
Age of plants - 26 days from sprout
Grow Type - coco
Grow Stage - Veg
Setup - 3gal pot with drip system
Light - 400watt led for vegg
Nutrients - AN Sensi coco
Medium - Coco
PPM - 700
PH - 5.8-6.0
RH - 50% to 55%
Room Temperature - 68-76
Solution Temperature - 68
Room Square Footage - 16
Pests - None Known

Problem: I'm having some leaf canoeing on the Badazz cheese. Could it be a N toxicity? Or to much humidity? I did lower my ppm to 500 to see whats gonna happen.
Any ideas?

I opened the first image with a photo editor to have a closer look. I'm seeing spots on some of the leaves. Take a look at the bottom of them to make sure you don't have any freeloaders of the insect variety.

Are you getting run off from this plant? If it doesn't have it's own saucer, try putting on a plate to find out. This could be under watering. A separate saucer from the community will let you know.

These should be checked before we go into the nutrient regimen.

Hey first thank you for the reply!!!
After seeing all your spot on the picture I went and go tru the plant with my 30x-60x magnifier and I could see all those little dot. Under the leaf there is bothing at all. Each plants have there own saucer as well with about 1/4” of run off in the saucer at every watering. To me it looks like clay pebble dust from the pebble, nothing was moving or anything... I took some closer pic with the magnifier, not sure if its gonna help. I can take better picture with a add-on lens for my iphone if needed.

All the leaves seem to be droopy. Are the roots extending through the bag into the run off, or is the bag sitting in the run off? These will cause over watering, one of the causes of droopy leaves.

If that's good, I'd suspect a nutrient excess. Nitrogen, or calcium are likely suspects. I'd do a thorough flush with twice the volume of the pot, and let them sit overnight. You can set them in a sink or the bathtub for this. In the morning, I'd start with a half strength nutrient solution, and re-evaluate in two to three days.

They do have pot elevator for each one and they get feed twice a day, once 6h30am after lights on and again at 5h30pm. I might give them to much cal-mag, specialy AN calmag is 4-0-0 and sensi coco already have lots of calmag... could be my issue

Just did like you proposed and Mix a new rez with lower ppm for few days!! @Old Salt thanks again
