Im not to familiar with drip methods. I have heard the nutrients for drip are a bit thicker than in dwc or rdwc. Not ready to go down that road but im sure grow diaries would have the trends im wondering about.

Have been noticing some rusty fan leaves showing up slowly over the last week ,

Added extra calmag as i expected this ...but no positive change , ph 5.8

Around 250ppm remo nutrients grow,micro,calmag


Seems to be older fan leaves affected first going up

What is the strain you’re growing?
Do you have enough C02 for them to breathe?
