Yes this is nute burn. Nute burn is the only thing to cause yellow or burnt leaf tips.. It's not on the edge of over feeding, it's being over fed.. Thus the yellow tips. If you continue to over feed you will have a nutrient lock out on your hands.
@Auto BobWelcome to AFN
What medium are you growing in? What nutrients are you using? What is your fertigation schedule? What is your water source and starting PPM? What is the PH going into the pot?
I will have more questions based on the answers.
Hi. I’ve been using canna terra pro for the soil with microhizel, half strength canna vega after the first 3 weeks now stopped that and only using Flores with a booster at half strength every other watering. Tap water with a ph of just below 7. Have been letting the soil dry out between waterings@Auto Bob

Ok what is the booster? Do you mean Canna Boost? If not stop using it.
This is mostly peat not soil so you have been running the PH a bit high and Canna recommends 5.8 to 6.2. I would work your way down over a few days to 6.1. Don't go down too fast.
This is a custom chart from the Canna site. The data I entered to get it is based loosely on what you have stated but you should go out and get it dialed in.

It is obvious to us that you have been overfeeding but I needed to see what it was that you are overfeeding to make a recommendation.
PH was too High, I would go PHed water 3 times then feed, repeat. The strength of 50% of the above chart should be ok Be sure that all products are at 50%. Then if the plant starts to get a little bit lime green in color go to water, water feed, repeat. Your plants shall live. If you want them to thrive add the other products on the chart.

Hi. Yes it’s canna boost. Thanks for the help it’s very appreciated I need to get some ph down and get on it. Are there any better nutes and soil you would recommend for autos? I’ve been told bio bizz is very good
