Why are the tips of my leaves yellow?

[Platinum Princd]

Hey I was hoping someone could give me some advice as to why I’m getting yellow tips on leaves. I’m in week 8 on this Dinafem WW autoflower she started to flower about 8-10 days ago. I’m using hlg 550 3500k for light.Using Gh Nutes. Ppms of feed is at 700... I’m using this chart to feed.


Could the yellowing of the tips be the plant outgrowing the pot there is roots sticking out the bottom like a mf but I thought airpots would prune these? Should I use a
Lucas method and see if problem consists more consistent watering? Any advice will help heres pics of the pretty lady

That is the very beginning of nute burn. It's nothing to be overly concerned about at this point. Many growers use that as a sign that they are feeding the max amount of nutes a plant can use. Just don't go any higher at this point.

Thank you I think it may have been because I let the pot dry out real nice and since it’s coir there was a concentrated amount of Nutes. Have now increased watering to twice a day so if that’s the problem it won’t persist thank you for the reply brother!
