Cela peut être un signe de la fin de la floraison de votre plantes. Mais le plus important c'est de regarder vos trichomes, ils doivent etre laiteux et ambre

Hey yes the plant should consume all nutrients before it is harvested, you want to have a clean product afterwards :-)

Lockout during transition Just a random question. I'm growing in a tent using coco and perlite. How do y'all keep your plants from getting nute lockout when they go from veg to flower? I seem to have this problem with every grow, no matter what I try with them. Thanks for any tips. ✌️ 💚 🌱

Yellow bright new growth New leaves on the Candy Kush plant #1 are bright green/yellow. This seems to have started when increased biogrow from 2ml/l to 3ml/l. Iron, zinc or sulphur deficiency? Only give calmag on next feed? Might have measured pH before adding nutrients so Faber wrong pH?
