Should these be trimmed? (pix)

These 6 Purple Kush clones were vegged for 4 weeks. They are now in the first week of flower under at 400 watt hps. Should they be trimmed/pruned because they are very bushy? What do you think? Pics are attached...

no need to trim untill buds form

they look good.....i think your yeild will be pretty heavy
good luck

I like to have all my trimming(pruning) done by day 14 of flower. Under a 400 with a plant anymore than 12"...it's good to trim out all the under brush so the plant doesn't waste food and energy on those bud sites that won't produce much more than fodder for the hash pile.

Drink!
