I reached out to the guy who makes the soil (Detroit Nutrient Company) and he said it's likely due to my lights. She's definitely getting worse fast
I just raised them from 18'' to 20''
Would those deficiencies spread that fast?
The lower leaves look good and green and I'm starting to notice...

I'm not sure at all lol, this is my first hydro grow. I just found some threads and went with what others did
4.5% CA in the canna A, 1.1% mag in canna B
I just mix it all in my res and ph down. 700-800ppm
So it turns out my Bluelabs ph pen was shot and giving me bad readings lol..... Just over a month old and cared for properly.
My res was somewhere between 4.0-5.0 for 1-3 days I believe :(
Got a new pen and got everything situated. Raised the lights just in case
I was thinking the same, especially since they're starting to go into flower. The second plant is much better, but also a little smaller
I'm struggling with it because I'm using autopots and a 12gal res. The ph constantly drifts up and I have to adjust every few hours lol
I assumed it couldn't be toxicity because I've been feeding the same ppm for weeks, but it turns out this specific problem takes weeks to show up lol
Currently at 850ppm, which is around 7ml/gal of A & B with 5ml/gal CalMag. Any recommendations? This is my first hydro grow
I appreciate it!
