On Friday night I always change my res. solution. I run it on the high side of ppm’s around 1500. Last Friday it was 1592 by Sunday down to the low 900’s this morning it’s at 603. Is there a way to figure which nutes are being used so I can readjust the ppm? It’s a gorilla glue auto this time &today it is starting it’s 5th week of flower.
If the pics don’t come out I’ll have to try again from my computer cuz this is the 1st time using my phone
