Hey yall , I am having some weird leaf curl on my Ninja Fruit sugar leafs.
Here is what I have
2 plants in Autopots (3.9gallons)
1 alien rift- 1 ninja fruit
Coco with canna nutes
A and b
Cannazyme
Boost
Pk13/14
Week 4 - 950-1000ppm
Water chiller and recirculating pump
Water temp 68deg f

First of all my plants grew way too big
I vegged for 4 weeks , my plants were 3 ft when I flipped and now there 7ft tall.
I topped and bent branches but she just stretched soooo much.

Anyway , the NF sugar leafs are curled and weird yet the AR leafs are ok.
I have some leaf burn from my QB550 light being too close, I had to dim the light to 80% so that the very tip tops were seeing 1100 to 1200 umoles.

If anyone has any ideas please let me know.
I have cut the nutes 100ppm to help stop the small burning I am seeing

The leaf curl looks like it might be from a bit excess nitrogen. The very high light levels start to mess with transpiration rates and exacerbate any over feeding. Just my quick take. I think you're on top of it.

You know I think your right, I watered down the nute mix to 650ppm for the next day or so then I will raise it back up to 800ish.
I have never seen a plant stretch as much as this one did. I swear it nearly tripled in size.

I've often seen this kinda behavior with autos during stretch. Usually it sorts itself out as the plant finds its intended height. Didn't add ferts to soil, so pretty sure thats not the issue.
