My Second grow: RQS Royal Critical Auto

That's over feeding, also called nutrient burn (burnt tips and edges). See how dark the leaves are? that is not normal, leaves should be light green, not dark, that's another symptom of over feeding. Stop feeding it, and give it plain water.

We love your greenhouse!!

Dear Fatanq, She is growing beautiful! Good luck! 👍💪 As Your Lady is flowering try to change the description of the week. The other thing is that it is very risky to spray neem oil or other pesticides on flowering plants... I am a rookie but that is what I hear from every response from veterans. Anyway, I wish You all the best with Your Lady. I would like to add that I love Your long and detailed reports on Your grow! 👍
