Light at flowering

First grow here and things are looking pretty good. Two plants in coco/perlite using FF hydro food. Plants are 12 and 14 inches now (pretty bushy -- from seed -- feminized white rhino; seeds from Herbie's). FIM'd 9 days ago and I'm still not sure I did that right, but everything still looks pretty healthy.

Lighting is two T5 fluorescent light panels; each has four 6500K HO bulbs (2 ft, not 4 ft). This is in a 3x3x6' grow tent, so not much room.

I want to switch the light cycle to 12/12 when the plants hit 18 inches or so, and that will be pretty soon, the way things are going.

Question... Should I also switch the lights to 3500K tubes at the same time? Howzzat work? I've ordered enough 3500K tubes to change everything out and the plan is to swap the tubes at the same time I drop the timer to 12 hours. Does this seem right?

I have a 2ft. 4 bulb HO T5 I use for seedlings.

I recommend keeping them short as possible; with a light directly over each plant, within 3-5 inches.

I agree^^^ I am trying to do a T-5 run now, if I can keep them short enough. They are in their 4th week and have been topped twice. I'll flip them early, probably after week 6. If they shot up to 18" I'd use HPS to flower. I have new T-5 lamps, both colors. I use the warm white for flowering.

Shovel, what ferts do you use?

Soil is reused from last grow. Added all organic amendments. Dolomite lime, dehydrated granulated manure, earth worm castings, high P bat guano, bone meal, Maxicrop, Excelerite, Plant Success, a small amount of compost and molasses.

Now I'm feeding a tea of 2 gallons water to a handful of Espoma Plant-Tone, Earth Worm Castings (EWC), compost and 1 Tbs molasses. The mix is pH adjusted for 6.0 - 6.5 and bubbled with air stones of one or two days. Then the pH is checked and adjusted to 6.3 +/-. I add Plant Success maybe once, twice a month. Plants get feed-water-water.

Cool, way to recycle. Is it chicken manure?

Same "shiite" here, reusing soil from last years vegetable crop. T5's here as well. No nutes to date since they are all seedlings. Need to update my equipment. Very pathetic to be honest!

Do you do anything to treat, or sterilize the used soil?

Sorry Token, I use hps for bloom, but do love a good grow!!

No, not yet. Will look into it when I t-plant. They're less than a week in the dirt. Will enhance the soil before I re pot.
