Nitrogen burn?

[Bigjmw32]

Plants are 24 days old and the leaf tips are starting to turn yellow. Also noticed other leaves appear to be turning yellow but still mainly green. I have not fed them anything, just PHed water so far. Tried doing a google search but could only come up with that it’s getting too many nutrients or not enough lol Any help/advice would be appreciated!

3 gallon FFHF with perlite

Looks like slight nute burn. Can see the tip yellowing. Nitrogen toxicity usually give u dark green leaves and the tips curl under. Yours looks fine maybe just ease back on the nutes.

Thanks for replying. I haven’t given any notes yet, she must still be absorbing a lot from the soil.

The plants are in happy frog. I read happy frog was a little easier on autoflowers and not so hot

My bad. Lil out of it right now. Your plants still look ok. Maybe a slight lil burn going but nothing too bad. Looks like your doing good to me. I’d keep going like you are until they tell you they needing something. I use coco so I can’t really say what to expect with the soil runs.

Honestly, nothing to worry about.
Soil looks to be just a little hot, but I would just continue your watering schedule until they show some signs of deficiency.
I wouldn't 'flush'.
