Ayuda mis plantas ya en su periodo final con hojas amarillas

I think its a lack of potassium. Start reducing your grow nutes and increasing your bloom formula. Check your ph and ec in the runoff to make sure you have no lockouts.

Hello BullWeed , this is magnesium deficiency. this you can see from the burnt edges of the leafs on the bottom of the plant and the yellowing on the top of the plant. Magnesium is an immobile nutrient, that is why the top is getting yellow and the bottom is burnt. Anyway, just add cal mag until you decide to do the flush before the harvest. Hope this helps ! 🚀

I'm going to guess is a nute burn, maybe this seed need less nutrients. You're using max dosage so it would be very strange to see a K deficiency because it look like it. check ph drainage
