You can certainly re-veg, but IDK how that'll affect your hermaphoditism. Stressing the plants helps cause it, and I imagine getting chopped back to a stump is pretty stressful. Affected my self-esteem something terrible. :sadcrying

Here are some thoughts, though...
1. The plant in question seems to have hermie tendencies, so I wouldn't bother with this until you fix other obvious potential hermie risk factors:

a) light poisoning -- 99% ain't gonna cut it, I don't think. When you set up your bloom room, zip yourself into it for at least 5 minutes with the inside dark and full light outside. As your eyes adjust to the darkness, you'll start seing your light leaks. Anything more than "starlight" is a risk. You should not be able to see any light, including ventilation ports, fans, etc.

b) stress caused by: improper pH (you gotta measure)-- top-dressing with lime and hoping for the best... pretty risky

c) improper nutrients

d) improper temps (gotta measure, for about $15 you can get a thermometer that'll record hi/lo readings from outside the flower area)

e) flat water -- when you boil or let it sit, it loses its oxygen. Gotta shake it back up to re-aerate, or just skip the boiling/sitting.

If you don't fix that stuff, you'll see me again! (Don't hate...:hippy

That 1% light's probably the culprit, tho'... HTH, Hermie :thumbsup:
