Phosphorus toxicity

[Jbiggs]

So I had a buddy make my nutrients while I was away and he went a little board with adding raw phosphorus. I flushed the ladies as soon as I found out but they aren't looking too great. I was wondering if I should do another major flush?
Also if i should flush with h2o2 or just go light on the nutrients with h2o2? I'm 3 weeks in.

Could you post a picture of your plants in your setup? A picture is worth a 1000 words

Unless it's in a solo cup or something really small that dries quickly, I wouldn't flush again until we get a chance to see the plant. And if it is in something like a solo cup you might consider transplanting it to fresh soil so you can start fresh. That's far more effective than flushing. Plus flushing can cause more harm than good with such a young plant, especially if it's in a big container, because it'll get really droopy for a long time.

It may not have caused the problem this time, but the most likely reason to see deficiencies is if the pH is too high or too low at the roots. Have you been checking the pH?

Lastly, is it possible to switch to nutrients made for plants like cannabis? They'll have the right ratios to prevent deficiencies as long as you keep the pH on point
