I was first in soil. Around day 6-7 tips were apparently yellowing. Turns out I was in hot soil. I should’ve known better to test the PPM before starting out. I’ve switched to coco and so far kind of so good but I’m not where I wanna be still- yet
Just because I had no clue about soil quality I started making RO water and calmag on my previous grows 7 years ago. Also used RO water for clones. Still ran into some stressful issues with discoloured leaf but all in all it was fixable and I got what I wanted in the end.
I read once upon a time that soil was the most forgiving to use but that might not be the case anymore(?)
