Im about 30 days into my first hydro grow and its going better and worse than I had thought it would. I find Im using my PH/EC/TDS meter a lot.
Part of that is using this chart to help set feed levels and diagnose issues.
Has anyone seen this chart before and do you know if it is based on any actual science or is it based on 'pot head' science and/or anecdotal evidence only or? Im not trying to bad mouth who ever made this chart, but a great deal of the advice/recomendations found in on-line forums isnt really based on evidence or rigorous testing.
Ive been trying to judge/adjust my rez nute levels based on this chart plus how the plants look. So far, the plants seem to like a little heavier feeding than the chart indicates, but its hard to be precise.
Its a pretty handy and well written chart, so I am hoping its legit
