Hey there,
the new shoots have extremely yellow tips (only the rippers). They are actually in the biobizz light mix and have not yet received any fertilizer.
I'm a little unsure where this could be coming from. Maybe dry spots? Or too much light?

Either light mix was not mixed well ( they preload that soil ) or its something else. Reminds potash overload.
Looks like toxicity, sometimes you have very light feeding phenotypes, maybe thats the case.
