Losing My Virginity. Growing for the first time. (Discussion Thread)

Welcome to my first grow. All help and insight appreciated, however, this grow is very simple and is being used as a benchmark for further grows.
I am growing 6 Blue Domino clones in 1.5 gallon pots which have been "LST'd" since shortly after they were potted.
MG .14 .14 .14 pre-ferted slow release soil is being used with MG .04 .01 .06 perlite at about a 70/30 ratio, and plain well water is being used.
They are under 12 4-foot 32-watt flourescent tubes using 384 watts and pushing almost 34000 lumens. During this grow, I will not be changing the 4100K bulbs (the only ones available at the local hardware store), but in future grows will be using the proper light spectrums for each plant cycle.
In the box, I also have a ionizing tower fan and will soon be using 2 dehumidifying eggs to help control the humidity as it is rather high when the box is sealed.
The box itself is about 2.5 feet wide, by 5 feet long, by 4.5 feet high. The inside is painted with flat white paint.
Thats about all the information I can currently give you.
Wish me luck!

Pics are now posted in my Journal thread here: https://www.rollitup.org/grow-journals/437784-losing-my-virginity-growing-first.html#post5820530
Plants are growing well, raising the lights 1 chain link (about an inch) almost every day. Now on the 12th day of flowering. Will need to make a small activated carbon filter to put on an exhaust fan still, but there is hardly any smell at this stage so far. They are being grown in my basement, and I am the adult of the house, so I am not too concerned about anyone giving my any problems, except for the in-laws (if they happen to stop by at the height of the stinky time).
I only vegged the plants for 15 days after I potted them, and they were 1-2 weeks old when I got them, so they had about a month of veg time. If they continue to grow at the rate they are now, they should end up the perfect size for my grow box.

I have a question though about watering. The soil is pre-fertilized, and when I water them, some water drains out of the pot. Now this water presumably has some nutes in it that it has leached from the soil. Would it be a bad idea to use this "ferted" water mixed with fresh water for the next watering? I mean, will the water turn bad so to speak as a result? Can I use this water, or should I use only fresh water every time I water?

And another about trimming or pruning. I would really rather not. I have only removed 2 dead leafs that came off with barley any tension at all. But if it would significantly have an impact on the main cola sites, I would be willing to consider it. There is a lot of green on the bottom that is not getting much light, and trimming or pruning would defiantly help the airflow through those areas, but I don't want to stunt the plants at all and was going for a "low as possible" stress environment for this baseline grow. But I have concerns of the airflow and moisture in the box and do not want to chance any major issues related to those.
Looking at the last few pics in my journal, what is your opinions about trimming or pruning these plants?

Major Update:

As a result of the high humidity and the initial over watering issue, there was previously a small issue with mold beginning to form around the opening near the door, and on the door itself.
This was taken care of by cleaning the effected areas with a clorox and water solution and by repositioning the fan, aswell as leaving the door open.
A little less than a week following that mold issue, I spotted a small while mold patch in one of the pots. I can only assume thet if was from a stray spore that settled there when I cleaned the box, cause there was no trace of any mold in any other pots.
I removed the effected soil and decided to let the soil in the post dry very well before watering again.

Soon I will be building a small activated carbon scrubber and purchasing a nice little exaust fan for the top of the box. I will also drill some "intake" holes on the bottom of the box and screen them off. I also am still waiting on those 2 "dehumidifying eggs" to arrive (currently a roaming postal strike going on in canada).

With the better air flow and air exchange, there should be no further problems with humidity or stagnant air in the grow box when the door is sealed.

Now that that is out of the way, I went and watered the plants tonight. But before I did, I wanted to make sure that I did all I could to make sure there was sufficient air flow under the canopys of the plants.

I decided I was going to remove all the hooks used to LST the plants (all 49 of them total) and trim any lower leafs that were not being exposed to sufficient light. And then I decided to remove any small growth from the bottom that had no potential to make it to the canopy. This was done also in hopes to give extra stimulation to the plenty of prime top sites that each plant has produced.

After doing this, I watered the plants well and let the pots drain thouraly and placed them nicely back under and lowered the lights.

Pics posted in journal.

I am expecting a stage of delayed growth resulting from the stress I just put them all through, but I am hoping that by doing so I have made the right decision and will ultimately be rewarded by my actions. I don't expect there to be much to update on for at least a few days.
Wish me luck.

Any feedback is greatly appreciated.

So I pruned and trimmed and watered the plants at the beginning of their light cycle last night. This morning, everything still looks good. I did not notice any droopiness and the plants did grow a little since. Well see how they look tonight when the light comes back on.

I was thinking about giving them some flowering nutrients on next watering. Considering that the soil is still active at .14 .14 .14, and the plants are now strong and large enough to not be burnt by the slow release ferts, I figure that the plants should be able to handle a little something extra to help boost bud production.

Considering I put about 30% perlite, does this make my pre-release nutes more in the range of .10 .10 .10?
I was thinking I want something in the range of 0-.15-0 to .05-.20-.05.

These numbers are dependent on whether the 30% perlite made my soil more of a .10-.10-.10, of if it has no real effect and is still more like .14-.14-.14.
Next watering is not until the 16th of june (they like 5 full days to dry out), so I have a few days to make a decision if I want to get it in the next watering.

edit: I found this http://www.homehardware.ca/en/rec/index.htm/Outdoor-Living/Yard-Maintenance/Fertilizers/Flowers-Vegetables/Granular/MEAL-BONE-NATURA-2-14-0-10KG/_/N-ntlin/Ne-ntc74Zlo6c/No-24/R-I5025590?Num=0

I think this is basically what I am looking for. I would prefer no additional N, but I will be getting whatever they had in stock that is closest to that.

I have decided that I will basically be following these simple instructions to build my activated carbon filter.
https://www.rollitup.org/indoor-growing/7074-easy-build-diy-carbon-filter.html

I will be attaching this to a fan like this.
http://www.canadiantire.ca/AST/browse/8/KitchenBath/RangeHoodsExhaustFans/BathroomExhaustFans/PRD~0522702P/Broan%2B50%2BCFM%2BEconomy%2BBath%2BFan.jsp?locale=en

I will have to reverse the wires on the fan motor itself, so that I can have the grill on the outside of my box blowing out (its a cheap fan and will look good, and I couldn't find anything like it with reversed air flow). I believe that this fan sucks through the grill like would a normal bathroom exhaust fan. But that sounds like fun, so for under $20, I'll give it a shot.


As always, any input is greatly appreciated.
Thanks for taking the time to stop by.
