Nutrient Lockout?

If the problem is a nutrient lockout you have only one solution, big flush until you see a low EC or a clear water if you haven't an EC-meter. Good luck and happy journey!

As they say............a picture is worth a thousand words! True "nutrient lockout" does not occur unless the pH is below 5.5 or above 7.5..............but without a diary..........

low N possibly too cold at night, if i am seeing some reddish color around edges and it's not an illusion of photography. Anything under 68F can cause autumn colors. the exact threshold may vary by plant a bit.

You only started feeding 5 days ago so I doubt it.

Your diary contains dick all for information and your ability to ask a question seems impaired. People can only go off of what you provide and if you provide nothing the quality of the answers is going to be reflective of that. Follow the feed chat the fertilizer provides and dilute it down to the desired EC/PPM I would link it to this response but I know you know how to google.

Absolutely 💯!
