Grow QuestionsPotassium deficiency?

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.

Nute Burn Plan. Lower light to 24 inches and turn on bloom switch. Flush soil with 8 litres of water (PH 6.5) per pot. Questions: will increasing the intensity of light increase plants ability to absorb nutrients, or simply stress them more? Is 8L water/ 10L pot enough to flush?

Yellowish color on most of the leaves and the condition did not change after watering. I suspect it's nitrogen deficiency or some pH problems. The plant is in pre-flowering, with sex being revealed. Will go into flowering soon. I watered it with 1.5l Any thoughts?

as you can see on some picture some leaves have burnt edges, others are 80% yellow-ish and few have yellow dots. I thought that I gave too much nutrients so I've been giving her only straight water for 8 days and more power light for 4 days. No improvement it's worse now. Please

The 2 Auto Dark Purps have a few leaves clawing. I drained the reservoir and filled it with filtered water and Flushed them with fox farms sledgehammer. How long should I flush? Should I just back off on Nutes or stay with plain water for a few days? Any help is welcomed.

What's wrong with lemon cheese? Is it overfed? Drain showed me 800 ppm and after flawless finish drain became 600ppm. Or is it my tap water (300-400ppm WITH FILTER)? Should i get reverse osmosis?

I think underwatering combined with the light being close has caused my issue. However older leaves have also dried up and died (but staying green). The way the leaf looks with yellowing though, and because a couple of leaf stems are turning reddish, maybe it's K deficiency?
