leaf edges browning and dying. K def, or nute burn maybe?

Back story, plant was N toxic. I was feeding TPS One as the bottle directed PHd to around 6.5. After N tox symptoms I flushed, and watered with just PHd water. Resumed feeding at half strength.

Plant is in soil. Temps usually low 80s daytime, 70s night time.

Appears nitrogen toxicity but also slight K deficiency.

So, would another flush and a foliar feed with bloom nutes be a bad idea?

The buds are frosty and smell dank. Don't wanma lose her.

Don't foliar spray anything while you're in flower.

Okay. So what would you suggest?

If I flush again to remove excess N, it would make the K deficiency worse. Assuming thats the issue of course.

Did those burn edges appear before flush?

over fed and burnt.

Done the right thing - flush and feed with a balanced nutes at half strength.

won’t see any repair but the damage should stall within a couple of days!

Yes the burn appeared after. they were clawing a bit, so I posted pics on this forum. Then I flushed followed by half nutes. The burn appeared after the half strength feeding.

When this grow is over I am probably gunna leave TPS One a real trash review. I followed the instructions to a the letter and while I am no expert, I am no noob either.

I had those thin brown wispy tips and just a bit of the brown edges in early / mid flower. I traced it to a slight k deficiency, like @hotrodharley mentioned. I think you're on the right track but consider upping k a little. Thing is, you're using a one part nutrient so you'd have to switch nutes mid grow. If you want to try it, try GH floratrio at around about 1/2 strength to start. You can go easy on the floragrow and up the florabloom a little.

I have switched to using Lucas formula in Pro Mix HP in flower. I use rainwater so add cal mag occasionally but my Jungle Juice has cal mag in it. No Grow. There’s enough nitrogen in everything else to cover nitrogen for the most part in flower. My first feeding after flip is half veg and half bloom. After that the Grow bottle goes away.

That’s one thing you can’t get from reading any label - experience.

I rarely use full recommend strength on nutes unless it’s mid flower and she’s a hungry girl!
