hydroponic nutrients

[dvs719]

How do you know if your nutrient levels are right in your resivoir when growing a plant hydroponically? this is my first run at it so i am unsure on this. Any help and or tips would be appreciated. Also I was wondering when I should start flowering my plant? I.E. What size it needs to be at etc.?????:)

you should have a ppm/ec meter to read the strength of your rez and more important than that is a PH meter.

Size of plant to begin flower is up to you. couple grows being logged right now that started flower as soon as clone was rooted.

Might be time to read a lil more. This site has more info than most peeps would ever need.
