Hi have a white widow that’s on day 45 and since pretty much day 10 she been showing these yellow tips.grow media is soil ocean forest I feed her with around 6.4 ish to 6.5 ish ph and her run off is at around 6.3 to 6.5. I first I thought it was potassium and the pictures you can see the yellow tips some leaves a little pale and a spot on one of the leaves. she is still showing new growth but at a slow rate
It actually looks like you might be suffering from a nitrogen toxicity.
When i saw his pic’s i knew that, that’s what it was. but i see that you have this taken care of. I’ll check in later
