Overfert?
ostrwahuiostarted grow question 5y ago
I'm following the biobizz fertilizers schedule and watering the plant with 1/1,5 l every 4/5 days.
Some tips of the leaves are yellow.
Do I need to worry? How should I handle the situation?

yes you have a bit too much nutrients going on, start using a little less next time and see if there are any changes. you should be ok. happy growing

Overfertilization, you have to give nutrient one times and water 3 in soil before giving again nutrient.

What have I done wrong and right?I'd love some critical looks at my plants, there are two in this grow. With only a few weeks left, I don't think there is much I can do to really improve things. But, please look at my pictures and tell me what you see wrong and what I should have caught. THANKS! 🙏6y ago
