2ft Plants Starting to Bud too Early,

[Rusty Trichome]

Plants go through growth-spurts just like kids. If you are using a 600w light, you won't want to let the plants get much taller in the growth phase, than they are now. Depending on the strain, the plants can double, tripple, quadruple in size once in flower. (Hybrids usually double or tripple) Effective light only extends about 4-5 feet with a 600 watter, so lower regions of the plant will start to fade as the light gets further away.

I'm a noobie at this too, but I will attempt this from all the reading I have done.

:wtf:

It is probably too late to get them back to vegging.

Wrong. Unless it's an autoflower strain, you can keep plants vegging for years. Check-out the re-vegging thread link in my signature.

but you run a huge risk of stressing the plants so bad that they go hermaphrodite on you and result in ruining the crop.

I think it would be a great idea to know what you're talking about before you risk leading other's astray.
