Potassium deficiency?

Misanthropestarted grow question 3 years ago

Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

hey there misanthrope, this is just your average nutrient burn you can tell by the burn on the tips. You have me worried about how you're talking about having 2.5 weeks left yet starting to flush soon. In hydro you wont need more than a day of plain water for a flush - that's kind of the point of hydro actually. Anyways, not a deficiency, try to reduce the nutrients by 0.5 or a bit less mL/L then work your way back up week on week . Hope this helps ! 🚀

I agree with dissnoof on this. Back your nutrients to an Ec of 1.4 max. When it comes flush I usually in hydro run a flush solution for 24hrs like flawless finish or Ghe clean then run water for 24hr then chop.
