Problems with my first grow

[sikar24]

Hi everybody, I have problems with my first grow.
So, my outdoor pot flower’s leaves started getting yellow from the outside. I have a 37l pot and I thought it would be a good idea to flush because I thought it’s a ph problem. It didn’t really help and my leaves also started to curl up. I’m currently in the process of making banana peel fertilizer which might help but I’m not sure. I need advice on why this is happening. Thanks for replies.

Looks like a nitrogen, iron, or manganese deficiency. You’ll have to provide more info on your current feeding schedule and some runoff numbers for ppm and ph to get a better idea of whats going on

I think she is hungry. What nutes are you using?

Looks to be a magnesium deficiency along with sulfur. Start adding epson salt to your feeding routine
