Gram per watt for a plant that vegged outdoors

1g/w isn't a guarantee. type of light you use will be a big part of that. even an inefficient light can reach 1g/watt. what happened in vege doesn't impact anything now except for the plant mass grown.. obvioulsy, if it helped you grow the plant larger, it should also increase your yield indoors with a larger plant -- this requires 'enough' light and coverage to realize. if you have too much plant mass for your light, you'll end up with very week buds or maybe a few good colas where light is strong and very weak, airy colas all other places. Depending on the LED quality, you'll want anywhere from 30w/sq ft to 50w a sq ft. If it isn't samsung lm301 diodes, lean twoard 50w a sq. ft. plant looks much larger than 2sq ft. so, i don'tknow if i'd recommend a large pruning as that will likely shock the plant at absolutely the worst time to do so. Keep light ever tallest colas, maybe tie a few in close proximity under that stronger coverage from the light. 4-6" x 4-6" per colas. Probably get your best quality on those under the more intense light.
