Friend,

The beauty of your own grow is part that you alone are able to determine when to start the flower cycle by switching to 12/12.

I have found that starting them any earlier than 28 days is a waste.

More specifically, I prefer to flower based upon plant growth levels rather than time.

Rule #1... You must imaging them growing 3X taller after switching to flower...and ask yourself if that will satisfy your desires.

There are no rules other than that.

For flowering clones, I wait until they are at least 12" tall. You will wind up with 2.5 - 3 foot tall plants...most of which will be pure flower stalk from your clones.

By all looks, it appears you have a ways to go. A long ways.

With all those black containers you have chosen, the heat retention from those reflectors is likely holding them back from growing. The reflector and the black bases can create a radiant heat zone that clones particularly are sensitive to in the root section.

Also, those were very young tender shoots taken as clones...almost bordering on too early.

These will take a while. They are no where near being ready to flower at this point.

I would advise that the grower wait until 12 inches of growth, at least, is obtained. It appears your focal point should be on getting the growth rate accelerated...but since you didn't ask, I won't advise.

You will have an awesum grow...but you need to wait and give them a chance to develope some girth. I would at least triple the fan action.

Give it another month...and...add some superthrive to you 6.8 water.

Attached are some pics I found on the internet of some 32 day old clones. They were placed in flower on day 28 at about 15 inches.

When they fully blossom, they will be single large 40" buds. Each 3.5 feet long bud will weigh at least one ounce each...cured weight. :dance:

Watch the main stem base. You will know its time when it is fat and thick like a white bic pen...you will need it to support the bud.

Good luck. :thumbsup:
