I would go over to the Plant Problems forum and make a post using the troubleshooting form at the top. Your plants look stressed and in need of assistance.

ventilation?

[dire1234]

i have a duct that is on the floor that brings in air, from out side
and i can post the problem stuff on the problem post area. i was trying to do scrog with them but i had to take down the screen they got to big

They look great to me. One thing I might think to check is the temperature in the room, if it's too high. You have it between 75-80?

You have a very serious problem there and those plants won't survive to harvest without attention.

Please DO NOT give advice when you don't know what you are talking about. You know who you are. If you don't I will be more than happy to point it out...

I'm moving this to 'problems' and calrifying the thread title.

There's a troubleshooting form at the top of the problems forums. Fill it out and we will see why the plants are curling under like that. One thing that I know already is that just an active intake is almost NEVER enough to give the sort of air exchange that cannabis requires. Standard setup is an active EXHAUST and a passive intake. You are going to want to change that, and add circulation fan(s) within the room to help with what appears at first glance to be suffocation from lack of air flow of the low leaves.

Actually, if you didn't draw attention to yourself by posting poor grow advice, I might not have noticed that you [ilovetv] were already banned under 2 other usernames... seeya.

temp in room is at a 72-76F i use last 2 tsp per gal of tiger bloom and tbl per gal of big bloom and 1/4 tsp per gal of open sesame and i use 1 tsp of dark energy , 1 tbl per gal of pure blend metabolic formula and 1 tsp super nova. ppm is about 1150 and ph 6 , they are in week 2 of flowering so i just change it over and co2 in the room just change from 400 to 1300 about. i started trying to do the scrog but when i saw the grow i had to remove the screen plants was getting to big even today then grown about 1/2 to 1 in. now i have notice some browning not on the edge but started in the mid of the leaf. any idea whats goign on and the plants look like they use up a gal of water or 1.5 gal a day about latle

GREAT info and there are some things that you can tweak.

When you run a CO2 boost, you should increase temperatures a bit. So instead of 68n/78d (standard), you can go up to about 75n/80-85d and the plants will simply transpire faster. NOTE!!! This only applies when you are running AMPLE CO2 from a REAL delivery system (not a yeast booster) and can measure the levels! Luckily you have numbers for that so phew. Correct me if I'm wrong, but isn't 1300 a bit high? I'm not real familiar with CO2 boosting so you might want to look for some info on optimal ppm/temp numbers.

Another thing I'm wondering about is your choice of ferts. The combination of fertilizers that aren't designed to work as a system can be troubling to many growers. Browning that begins in the center of the leaf often indicates potassium being locked out. Closeup pics would help nail that one down. You're running 6 different juices in the res and that is quite a cocktail. What about your water source? RO/tap? If RO, where's your CalMAg?

As for the venting, you are venting AND running CO2... you should read up on the concept of the sealed room. Search user 'tranoble' or the terms 'sealed room' for some really neat info on that.

How is the temperature of your res? Is the res up off a cold surface such as a concrete floor?

We'll get this sorted.
