pruning ?

[Des Pot]

hiya, last grow i made some elementary mistakes but back on track with this grow.These beauts are BLZBUD from Serious Seeds(Feminized).I am using an 8 pot Panda aero-system with the 3 part GHE nutrients that came with aero-system.Light is via a 600w HPS with dual spectrum grolux bulb.THEY ARE ONLY 6 WKS OLD FROM SEED. They have been on 12/12 for 11 days now.
As you can see from pics things are looking very crowded in there. Should i prune for better air-flow? If so , how much should i prune without compromising yield??
the tallest plant now stands at 38 inches!!

Pruning is for hedges, not weed.

Topping should be done while the plants are in the vegetative growth, not in flower.

Every leaf you remove, the plant gets less light.

Use a fan and get the air moving under those plants. Mine are just a bushy, but a good fan will move the leaves slightly and get air moving all around your plants. Moving the air is what you should concern yourself with, not cutting your plant up.
