Need help , burn plants problem

[Anonbl]

Good morning, I have a hard time with my last grow first I have a light leak because of the humidifier light but I fix it thank to you guys, but now I have a bigger problem with the leaves showing some burn the light is 900 PPFD so i don’t think it would burn the leaves like that but I give it cal mag five days ago and I spray it with neem oil three days ago I don’t know what cause this is it nutritious burn or maybe the neem oil or another problem that my third grow and it’s my first time having this problem and every day it gets worse any advice would help. Thank you

I think your pots are way too small. I don't think the issue was from the need oil. Just at first glance, I would suspect nute burn or nute lock out.

May I ask. What is the PH of the water you are giving them?
