My leaves look like tornadoes man

the ec on all of them are consistently 1.1-1.2 while my input is 1.6

It’s a genetic trait.

Alright so I had a eureka moment just now drinking some wine, I could of course be dead wrong in my assumption but does this make sense:

The PH and the EC were BOTH going down in my hugo blocks with good dryback between feedings, and good dryback overnight. I thought this was unusual to see both numbers go down but I made a decision that it's because I was letting them dryback TOO much, so I increased irrigation length..this helped the ph stay stable and the EC would still go down. I thought this was an improvement and maybe I just needed to feed stronger.

Then today I started to see a progression of what looks like a calcium deficiency, that I thought was light burn at first. Some brown dead spots on leaves and the newer growths being pale and burnt on the edges, as well as some tip burn.

So my a-ha moment was remembering calcium is a cation, so if the plant is uptaking all the available calcium in my nutrient mix it would lower the ph in the root zone as well as the EC (is this correct?). And since I wasn't feeding ENOUGH calcium, it showed deficiencies. Am I on the right track here?

@Anthem got my brain jogging because he runs the same lights and saw a correlation between the light and calcium

Would also love your 2 cents @Aqua Man and @sshz since you guys are more studied in the way of plant science. And one of you also has the gavitas. Or anyones 2 cents for that matter.

Twisted leaves such as yours is a sure sign of over fertiliation....... so either your ppm is too high or you're letting the cubes dry out too much. Then when you're plants are having issues, the intense LED's exacerbates other issues. Raise the LED's a bit or dim them to give the plants a chance to recuperate.

Lmfao!!!

It only took until page FN 2 to post a correct answer. Genetic trait!!

Wtf happened to this place? 6yrs ago this place was hopping with great growers and mods, now look at it.

I better be quiet before I get banned again and everything gets deleted.....again
