I have referenced more than my fair share of charts, graphs, trichome pictures, ec data, vpd data, and many more during this past grow. I thought it would be a great idea to post this data in one discreet location. I apologize in advance if someone has already done this. If so, I’ll delete the thread. Feel free to post any images that might help with growing cannabis. Some will be self explanatory. Feel free to give an explanation.
Soil pH on below chart
Above chart is for general vegetative VPD
Below is a chart for anyone using FF nutrients running a Hanna 500 ppm meter, as FF uses ppm 700 for their feeding schedule. This is a common problem when using FF nutrients. Most people are using Hanna meters, because most tds meters sold on Amazon are Hanna 500 ppm meters. Credits for the below image go to @Bobbydigital
