Am I ready To Flower?

All were clones taken from from mothers of supposed rhino & superchron strains 6 weeks ago.

400w HPS with metal hailide conversion bulb
Using nutrients called "sugar-peak" which -- recommended by local store.
pH is at 6.5 using natural down, nute tank is @ about 76 degrees F during day

we plan on using the flowering formula also made by sugar-peak, but adding a little something special in the form of monster bloom, and swapping in our 400W HPS bulb. We are thinking our space is a little limited so maybe we should flower now. Most plants are already tied town.

Mylar to come before any changes are made, you betchya!

you should of probably of started flowering 3-4 weeks ago as your plants are going to get a lot larger and you dont really have the room or enough light to be flowering large plants.
you might consider topping and removing alot of limbs or pruning just so you can even up the canopy and have a little more control of the growth that you will get during flowering.
generaly you will not start feeding flowering nutrients until 2-3 weeks into 12/12 .
