Hey Hydro, how's it hangin'...? Nice to see ya in soil. :thumbsup:

Looks to me like too much nitrogen. It can make the leaves deep dark green, burns the edges, and fights against the plants desire to flower. Some use it late in flower to 'green' the ladies up. Any chance of going with a more cannabis-friendly nute next time, or possibly cutting the MG Bloom dosages in half? Are you using a separate bud enhancer too? (Sweet, molasses...) How about micronutes?

If she isn't showing stress-nanners yet, a proper re-veg would be fine. Trying to keep her in prepeptual flower will over-ripen her. When they get over-ripe, they could start to throw-off some nanners, but then they die.

I'd go with a re-veg after harvest, if possible, and make a "big bush of a plant for next year". You could take clones from her regularly, to keep ya going thru the winter. There's two examples of re-vegging in my sig, if interested.

The problem with growing big plants, is how to keep the lights within usable range. (harvesting clones from her can help keep her size in check) For example...2 CFL bulbs may be fine for vegging a 1 foot plant, but do you have a plan as to how you would light a 4 foot plant?
