Dear Community, I would really appreciate some help! I'm growing on soil only and in the last days of veg 1 of my 3 plants started to show some discoloration in light green - brown mainly on older fan leaves. I repotted to 7L, but it didn't change anything. What can I do? Thanks!

Por el color que tienen diría que es un exceso de de riego con fertilizantes y eso causa bloqueo de raíces. Lo mejor es lavar raíces y empezar los riegos con todo bien calibrado, ph, ec, etc..

Looking like a classic CalMag issue, you need to buy specific nutrients to get rid of this, else the whole plant will look like that.

It’s looking like your experience a calcium issue. These plants really use a ton of Calcium to grow and it is needed to provide them with additional calcium as they grow. Most bottles of CalMag will do, just follow the manufactures reccomended dosing. Luckily, this is one of the easier issues to fix. I hope this helps.

it looks calcium deficiency to me. If you're using RO water, add more calmag. Good luck!
