it's a shame, I could have done better, maybe next time :-)
Before updating you with the last 2 videos I would like ask you one question.
Is it recommended for a beginner focus on one type of genetics or is it better take experience with different types ?
Update about nutrient overdose:
the PH of the ground has dropped from 7,2 to 6.4.
yesterday they took the last irrigation, just water. Can I start giving nutrients again the next time I water them?
No because your substrate is saturated with nutrients still performs one or two watering with clear water with a pH of approximately 6.3
This should drain your substrate
May the strength be with you 💪
