My two girls have for a couple of weeks been getting yellowing of the larger leaves. I’ve tried checking for root rot. None that i could see. I’ve repottet them to a larger pot(from 35 l to 60l as they both did outgrow the old pot. They have been getting fertilizer about once a week.
Can anyone help me with what im doing wrong?
Depends on various factors like genetics, water pH, initital substrate or fertilizer regimen. People usually don’t try lollipopping with their first grow. Once you know your plant needs you can do these advanced technics. I don’t think we see a root problem here, that looks different. OPs “allround” fertilizer was just not goot enough.
Here’s a chart about fertilizer in the main phases:
As you can see, they can use a littel bit of N in flower, but if there is a major defizit they will pull it from the leave-reservoir.
