Tomato Plants are not producing....

[T'Mater]

So how often are you all changing your nutes? And when you change your nute's do you completely drain your tanks and start over or ?

I tend to change mine about 7-10day's. Is that too soon? And when i change, i completely empty my nute tank and like i've mentioned before, run pure water through the system for at least 15mins.

And when do you know when to increase, or when to switch over from more of a growing formula to a bloom formula? I assume now you all are waiting till you see the first flower's start before switching over.
