Is it nutrient burn?

GuniGugustarted grow question 3y ago

Week 9 I noticed orange/brown spots on leaves and tips turning yellow. Is it because nutrient burn? Was feeding them with all the Biobizz nutrients by their schedule. Second day, 10 week I flushed the plant. Should I continue flushing 3 weeks before harvest?

Looks like it's asking for some more p and k mate. I'm using BioBizz atm and they are not the most concentrated products out there. If you've got topmax I'd up that to 4ml/l the stuff is practically water with a tiny amount of pk per ml. But you could keep flushing it for another 3 weeks till it's finished, won't do it any harm.

What are these yellow tips on my leaves from? Have fed it water with organic nutes once to twice a week, the only time it was given pure water was a few days ago. I am using recommended doses. Could this be nute burn?

Burning Edges/Yellowing and Drooping?The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!
