8k ebb and grow.. first attempt at hydro!

What's up guys, first post here at icmag..

I'm very new to the size of this set-up, and even newer to hydro so I have some questions along the way

anyway here's a little info on the setup...

room is 10x20 with 10x16 being utilized right now, plan on adding an additional 2k on top of the 8k right now and filling out the whole room.

Running 40 plants with two reservoirs using an ebb and flow system.

Have a 3 ton ac to cool the place (gets hot inside the warehouse during summer) and 1 12" fan on each row of four lights, and one 12" venting the room (although the room is not sealed atm so they all three vent)

Have a sentinel controller and 12 burner, which will be turned on during flowering. The room will be sealed at this point as well.

Temps stay in check around 75 degrees, lights are on 24/7 atm and will be switched to 12/12 in the next day or two

any way enough babbling here's the pics already

I went to user menu- old gallery. Then I tried to upload photos, every time I try and upload I get an error message. Am I doing something wrong?

The message I receive is

/data/web/icmag/icmag.com/www/gallery/uploads/274367: Error creating directory (check permissions).

Please notify the System Administrator.

Some snaps of the room...





Here is the big boy A/C and the intakes drawing in air from outside. When the burner is turned on we will attach the ducting to the two first hood, sealing the room.

House and garden for the nutes.

Was running the whole line, have since dropped roots excel. (used until about 2 weeks ago, I don't think it's necessary after they've gotten their roots established..)

Thinking about skipping the shooting powder and just using maxi and koolbloom.. just because of the $$ difference

Here are the pics of the yellowing I was talking about..



and a different plant



STATS from today from the res that hold these plants..

EC 1.7
Temp 60 (colder than usual..assuming because the lights were out for 12 hours for the first time)
pH 6.5 .. a little high but I brought it down to 6.2 with some natural down..

EDIT: The drain pumps (in the controller bucket) failed and the buckets were filled for several hours, and they all appeared to be over watered. Any fix for this? They seem to be perking up now..
any suggestions??
