Welcome back.
Do you know your runoff PPM? What are the specks all over the plant?

yellowing at the leaf tip Ppm 500,600
Specks look like water all over the leaves.
Not a good idea to get the plant wet.
Yellow tips are usually too much nutrients.
Midwestguys question is important. Do you know your PPMs ?
Is that going in or what comes out?
@Spiney_norman and @MidwestGuy are on the right track with “Do not get leaves wet” and yellow/brown tips is indicator that nutrients are at max+. If you are using added nutrients, it looks like you may have started too soon. Good quality soil can feed a plant for up to 2 months easily without adding more.

No major damage done. Just try water only for a couple of waterings and then check runoff PPM.

Personal experience here using bio bizz line of soil and nutrients and I have to be honest they are a pile of s**t. I went with coco this time with canna nutrients and they are doing a lot better
